Harry, I WOULD have auctioned it, but only with putting in a strong caveat that it would require much paint restoration, and that you should not bid unless you don't mind the defects or can live with a heavily restored poster.
It's kind of like the faded Gilda that was auctioned on eBay. My honest description of the defects would have chilled the bidding.
This is why people rarely give me heavily restored items. They'd rather give them to auctions with fuzzy condition descriptions that "miss" a lot of restoration. I can't tell you how many posters have been consigned to me where I have to tell the people that the borders are new, or it is a re-paint job, and they tell me, "But when I bought it, it was described as having minor fold and border restoration and being in 'fine to very fine' condition"!
Interesting that Poster Mountain completely agreed with me. His answer was based on trying to restore these before, and seeing how only paint could cover the extensive foxing on these high gloss posters. Mine was based on seeing how similar ones turned out when all the top restorers tried to fix them without paint, and failed.
