No content with ripping off only Topps, Upper Deck also took a page out of Kellogg's book and had 3-D cards in both the 2003 and 2004 set. They also included these in the base set instead of having them be an insert set. I'm not sure how short-printed they are but I've never seen any of these three on Ebay, Sportlots, COMC, or Beckett.
They are now on my most-wanted list. Anyone got extras of these lying around??
