This picture is believed to be the only photograph of Vincent Van Gogh as an adult.

An art historian claims to have identified the Dutch painter among a group of 34 men who posed for the image in Paris in 1888, the Daily Mail reports. 

Until now, the only images the world had of him were those drawn by the artist himself because he was famously camera shy.

Other photographs had only been taken of him when the Impressionist painter was a teenager.

But Antonio De Robertis, a leading authority on the artist, believes one of the men in the Paris photograph ‘is, in all probability, Vincent Van Gogh’ after comparing the image with his self-portraits.
