Louis van Tilborgh, curator of research at the Van Gogh Museum in Amsterdam, said the painting was unusual for the 19th century impressionist, depicting large human figures in a landscape.

I just noticed that the curator himself thinks the painting was unusual for a Van Gogh.

I would like to know what markers they used to authenticate it, other than the art store stamp and the pigments. What about stylistic markers?

About the Cormon atelier photo, I'm trying to find out who some of the artists are.

I see Cormon himself, at the easel. Van Gogh is NOT the one crouching in front of Cormon with an easel, contrary to what another internetter thinks. If you follow a straight line from Cormon's head, Van Gogh is 3 heads behind him (with a long space between Van Gogh and the person in front of him). I also see Toulouse-Lautrec, right in the front with a bowler hat. As a comparison, see this [one photo contains nudity - NOT safe for work - scroll down to see Toulouse-Lautrec - don't click if you're offended by nudity].

If anyone has any ideas on who some of the others might be...
