Vincent van Gogh and Toulouse-Lautrec
After his arrival in Paris in March 1886 Van Vincent van Gogh was introduced by his brother Theo in the circle of the impressionists,
and became a friend of Toulouse-Lautrec. They experimented with the style and techniques in the art of the impressionist and post impressionists.

https://www.vangoghmuseum.nl/en/collection/s0274V1962:
"Vincent van Gogh was a good friend of Henri de Toulouse-Lautrec, whom he knew from the studio of the Paris artist Fernand Cormon where the two painters took lessons."

https://www.vangoghmuseum.nl/en/collection/d0693V1962:
"The French painter Toulouse-Lautrec met Van Gogh, who was eleven years older than him, at Fernand Cormon’s studio, where they were both taking lessons.
They probably worked together intensively for a while, as the style and technique of their paintings in this period look very similar.
Toulouse-Lautrec sprang to his friend’s defence at the exhibition of ‘Les Vingt’ in Brussels in early 1890.
Van Gogh had submitted six paintings, which caused a furore during the opening.
Toulouse-Lautrec was so angry about some of the negative comments he heard about Vincent’s work that he almost got into a fight with another artist.
The two painters might have seen each other one last time a few months later, when Van Gogh left Saint-Rémy and travelled to Auvers-sur-Oise via Paris.
Little else is known about their friendship."

http://www.vangoghroute.com/france/paris/atelier-toulouse-lautrec/:
"Vincent met Henri de Toulouse-Lautrec (1864–1901) while studying at Fernand Cormon’s studio, and the two men became friends.
Though little is known about the friendship between Vincent and Toulouse-Lautrec, they must have worked together intensively in the early months of 1887
When Vincent left Paris in February 1888, he probably wrote to Toulouse-Lautrec once from Arles,
but as far as is known, Toulouse-Lautrec never replied, and there was no further correspondence. The friendship was by no means over, however.
In July 1890, when Vincent was living in Auvers-sur-Oise and paid a visit to his brother in Paris, Toulouse-Lautrec came to see him, and they had a good time together.
After Vincent's death, Toulouse-Lautrec wrote to Theo that Vincent had been a good friend of him."

"Relationship Henri de Toulouse-Lautrec with Vincent van Gogh
In February 1886, Vincent van Gogh left Antwerp for Paris, where his brother Theo lived. There he enrolled in Cormon's Atelier and became a friend of Toulouse-Lautrec.
For two years they painted and exhibited together, influencing each other's work, but in February 1888, on Lautrec’s advice, Van Gogh moved to the south of France.
They spent one more day together in July 1890, during Van Gogh's last visit to Paris.
It was through Emile Bernard that Van Gogh struck up a closer friendship with Henri de Toulouse-Lautrec and Louis Anquetin, whom he had also first met at Cormon's.
Van Gogh had paid regular visits to Toulouse-Lautrec's studio in Rue Caulincourt, Paris, just around the corner from the brothers Vincent and Theo's apartment, to show his work."

In Van Gogh's period in Paris (March 1886 – February 1888) the colors of his pallet are influenced by the impressionists.
He made there more than 200 paintings, among them sights in Paris, especially in Montmartre.
See: http://www.vggallery.com/painting/by_period/paris.htm,
Much work by him was unmarketable and got lost or is missing.

   
Two "Vincents" Picture #1 and Picture #2

A Dutch businessman gathered paintings, etchings and drawings in the first half of the last century.
The collection consists of unsigned work of good quality. An exception are two paintings signed with "Vincent" bottom right.
The paintings are two market scenes in the clear spring colors of the impressionists.
The two signatures bottom right have very much resemblance with Vincent van Gogh's signature on the drawing Paysanne au bassin dans un jardin. September-October 1885.

To get more information about the two paintings, this website was published on the Internet 22 June 2006.

June 2006 printed A4 photographs of both "Vincents" and the link to the photos on this website were presented to the experts in the Van Gogh Museum in Amsterdam, the Musee d'Orsay in Paris and the Kroller-Muller museum in Otterlo, Netherlands with the question whether the two signed paintings are work by Vincent van Gogh.
The answer of the Van Gogh Museum July 17, 2006:
"We have carefully studied the material you have directed, and based on stylistic characteristics believe that this work can not become Vincent van Gogh attributed. "
July 2006 the VGM examined only the printed photos and did not examine the photos on this website.

The following opinion was provided on December 2017, after being almost 12 years on the Internet, by
        Janet G. Smith
        http://www.jgsart.com
        Janet's CV
Janet was the first to discover December 2017 on this website in the top left corner of Picture #2 another, on the first layer a for the greater part over painted signature:
"TL Vincent": a monogram of Henri de Toulouse-Lautrec and the signature Vincent.

Her sole opinion is the paintings may in fact be two collaborative paintings of Vincent and Toulouse-Lautrec in Paris, estimated date 1886:

"Picture #2: Review the sky top left for the artist's name is again written "Vincent".
Again in the sky to the left of "Vincent" signature appears to be "TL"
The works may in fact be a collaborative works of Vincent and Toulouse-Lautrec
I would estimate the date to be 1886 for both pictures.
This is my sole opinion."         This_is_my_sole_opinion_2017-12-18.pdf

March 2018 Janet found also the specific letters of Vincent van Gogh where he wrote about the three paintings:

"The 3 pictures are of 1 specific event or location and Vincent van Gogh wrote about it in his letters.
I have found the specific letters.
I have just started to review Toulouse Lautrec's letters.
I have identified the scene in relation to the artist "Vincent van Gogh" and the location he painted in all 3 pictures-
your 2 paintings and the other 1 painting.

I am aware of a fourth painting that I reviewed almost 18 years ago that was not visibly signed,
but in a photograph you can read the artists name 'Vincent'.
It is study of one of the buildings Vincent Van Gogh admired in the same town=location.
There is no indication of any artist but Vincent Van Gogh in the picture.
The palette is identical for the buildings in all 4 paintings. "

           So two times "TL Vincent" on the first layer under the blue sky.
     

Janet asked to contact the Musee d'Orsay and the Van Gogh Museum with the new information
           - The Kröller-Müller Museum has not the required expertise and referred to the Van Gogh Museum in Amsterdam.
           - The Musee d'Orsay in Paris stopped appraisal of paintings and referred to

The third painting, Luisa's Impressionistic Painting, Picture #3

Luisa, living in Venezuela, bought a painting a few years ago in Caracas, also a market scene, in the clear spring colors of the French impressionists.
Nobody, including the Van Gogh Museum in Amsterdam in 2011, saw the "TL" monogram at the top left and could tell who painted it.

March 2017 Luisa found this website and saw the similarity of her painting with the two "Vincents" and asked me if her painting was made by the same painter as the two "Vincents".
Luisa's impressionist painting has been standing since Feb. 2018 also on this website and it also has the "TL" monogram of Toulouse-Lautrec in the top left corner.

Janet G. Smith's opinion and sole opinion is that also this painting is the collaborative work of two artists, Vincent van Gogh and Henri de Toulouse-Lautrec. The date is 1886.

The painting was examined in 2011 by the Laboratorio Scientifico del MUSEO D’ARTE E SCIENZA. Milan.
See: Results of scientific tests by the Laboratorio Scientifico del MUSEO D'ARTE E SCIENZA. Milan. 09/06/2011
The Laboratorio Scientifico dated the painting's oldest coat of paint as being made in the second half of the 19th century,
but the characteristics of the colors painted afterwards refer to the first decades and the middle of the 20th century.

The Laboratorio Scientifico del MUSEO D'ARTE E SCIENZA in Milan could not establish the identity of the maker, nor did it recognize the "TL" monogram at the top left.

This painting was probably edited around 1914 by Gustav Prucha (1875-1952) while he was in the Netherlands and used by him as an example for a number of market scenes in the Netherlands.
The people on the market wear clogs there!

        Van Gogh's "Summer late 1886, View of the roofs of Paris". It hangs in the VGM as a work by Vincent van Gogh, but it is not signed;
        it does have a Toulouse-Lautrec monogram "TL II" on the base layer in the top left corner.
        The same "TL II" Monogram as on Picture#2 an on Picture#3 in the upper left corner.
        On 20-02-2020 to prof. Dr. J.L. van Tilborgh proposed to investigate this.
