I can't see them going for anywhere near that price, can you?
It's a heckuva popular, praised flick. I think it's safe to say that autographs and items with provenance of that quality will do best in the long run. Hopefully for the people who bought them, and thinking about my
Avatar lenticular purchase, I hope the best stuff for all movies like that will continue to sell in the future at an increasingly higher rate than inflation!
Living in the present is best, IMO, and most of the people who really love stuff like that probably don't worry about the potential future $ as much as investors.
