Actually, I should revise my above statement... I still agree that this poster *needs* restoration if the intent is to preserve and/or display it.
However, after some research I'm not certain it will increase the value enough to to make it worth your while if you intend to sell it. Bruce has a record of one of these selling in 2003 in G-VG condition for only $238.50. If it was restored on linen I would imagine it would go for a similar amount in this market, if not a bit more... say $300 to be generous. After Bruce's 26% cut at that selling price, you would pocket $238 minus any restoration costs (which would probably be ~$250 if not more). So you are out of pocket at this point, especially after shipping to/from... blah, blah, blah. Contrast that will selling it as-is where you might get $100 or so, more if you are lucky.
Anyway, I just wanted to clarify as I thought this might sell for closer to what the Universal Horror -- Abbott/Costello joint pic posters go for... which this title doesn't.
