I had a customer bring in a vintage ad art poster last week complaining that the art gallery he had purchased it from, who had "thrown in" the framing, had neglected to show any of the white border on the poster and he wanted to have it reframed so he could see the border. I had to inform him that the border was gone. In reviewing the piece it looks as though on the sides and bottom the sides of the original paper are intact. The top border (maybe it wasn't square?) looks to have been cut, however. My guess is that the cut at the largest point would not have removed more than 3/16" of the original poster. I do not know enough about how these posters are valued to know if something like this would depreciate the value of the poster. My customer told me he paid about $10,000for the poster including framing. Just an aside, the framing was a total botch job.
