I believe many collectors, like me, of more scarce, older posters are less worried about condition compared to just finding a poster they like from back then. Of course, there is the preference for unbacked vs. linen for some collectors, though good luck finding any copy of many of the older, rare posters, right?! I bet someone like Sue Heim could sell someone a nice frame and give a grade, if someone really wants one, for a competitive price compared to a grading service! If you're T, just a frame or two where you can change out posters now and then saves a lot of money. If you're like me, and like to display your posters, I say spend the money on the frame instead of grading! Will grading posters via a grading service bring outside investors into the hobby like with comics? Geez, I hope not. Okie
