This is a fairly known photographer I found several years ago in a compilation edited by Taschen, unfortunately I never took note of the name and now, after hours of googling, I cannot find it. The photo, indeed a hand-colored-photograph, depicts a seminude male walking towards the observer wearing what seems an ape mask or a deformed version of a human face. Another feature I remember of this photographer is a tendency to work with tattooed people as well as representation of circus and freak-shows.
Based on style, my first hint was that the author of the photographs was Jan Saudek, but I cannot find the mentioned photo in his catalogue. Any idea of who might be the author or the name of that photo?
Although this questions seems off-topic at first, similar questions made it into this page and got positive answers:
Who is the Japanese photographer famous for long-exposure daylight shots of busy intersections? Who is the photographer of this black and white photo of two female nudes standing over a pile of clothes?
