This was a freebie poster, one of two, that came with a 48-page paperback book. There was one on E-Bay awhile back. The posting included the book and both posters. Unfortunately, it had no bids at less than $10.00 (including postage), and, sadder still, it got no views at all.
Judging from what I saw, it looks as if your poster is, indeed, faded. I would say keep it on the wall and enjoy it, but don't plan on selling it for more than a dollar or two.
