As one who has spent time with the construction of the postcards I can tell you that the original design, while close, wasn't going to withstand the stress of transporting, assembling, using in the show, and disassembling all the way to the end of the season. Another problem was that the postcards being as large as they are would not fit through a fair amount of the gates to stadiums. There were some other minor issues as well. All of those design issues have been corrected and the postcards should be out soon. They are really cool :) – I think they are really going to add to the show by helping tie the storyline in.
