I have the attached pencil drawing purportedly signed by Chagall. Does anyone have an opinion as to whether the signature on the envelope closing flap is authentic?
Hard to tell from the image on the PDF document. I would have to see a clearer image to give an opinion. There are so many Chagall fakes out there, it is alway difficult to be 100%. Most fakes have the 'g' joining the all in Chagall, whereas a lot of his in-person signatures were mostly separated.
