I'm wondering if anyone could help me authenticate this Marc Chagall Lithograph? From my research it would appear to be the Jerusalem Windows Tribe of Issachar lithograph. In the bottom left corner it is marked H.C. for Hors Commerce "Not for sale" and then signed in the bottom right. I've found that there were 150 numbered pieces 1 - 150, another 150 in Roman Numerals and 10 artist proofs. The colour of the other pieces I've seen are different than mine (all others I've seen are green). I'm wondering if this was an early proof that he later changed before the final work was complete or is it a fake? The signature is extremely close to others I've seen with the exception that he hasn't underlined his name. I have seen a few examples in my research showing his signature without the underlining at the end of the last L.
I wouldnt worry so much about the underlining, as I have seen examples of his without the underlining but unfortunately I would worry more about the size, placement and flow of yours
yep a that would be about the right hammer price altho Christies, surprisingly can often get things wrong
