Trading card companies continue to push the envelope as they look for ways to drum up interest in a crowded marketplace looking for 
something unique. The latest effort comes from Panini America, which on Monday debuted its 'World's Longest Football Card' creation. It's not really a card, but rather 36 signed cards joined together in a sort of cardboard accordion that measures longer than eight feet.
Numbered to five, the issue features large swatches and autographs from the NFL's young stars. Too large to fit into a pack, they'll be awarded to collectors who pull special redemption cards from packs of the company's new National Treasures football product.
One of the five will include inscriptions.
The company showed it off in a video released on Monday:
