That's cool that they came flat and in card holders, though I'm sorry yours got dinged. I haven't ordered one due to space limitations mostly. I also, like most, have limited financial resources and, though $50 is very reasonable, I figured I'd have to frame it if I bought one. Do you think the uncut sheets could be nicely displayed in the card holder without looking too "cheap"?
The toploader case is still really flexible and not real rigid due to it's sheer size. The uncut sheet does not take up the whole case either, there is room left over. I think it could be displayed that way but you'd have to be careful to attach it to the wall along the top so that it does not bend anywhere on you. Maybe you could make some sort of framing along the edges of the case for a better look?
Ideally, I am going to frame one and inside the frame I will cover up/crop out the factory machine markings for color coding and cutting along the edges by using a matting material. This way, the only thing showing will be the card set and it will be really cool to see the whole series at one shot.
By the way, it's not as big as the sketch or series poster are. It measures approx 20 inches across by 21 inches high. I rounded off to the nearest inch.
