edacra I mentioned what's considered acceptable for movie posters in the REA thread.
I'd like to see alterations and restorations become an acceptable practice - that is to say, I would like to see it above ground, and declared up front. Let the restoration guys come out from hiding so we can knowingly chose what we want to pay and how it may decrease/inscrease a cards value. We know it's going on. It's an art in and of itself. Don't hoodwink people though.
As for creases - I'd say any "process" or specialty work is a no-no and alters the card. If you're just sticking it under some books, or pushing on it with your fingers, that's the equivalent of a dust off.
