Production Error in the 07-08 Fleer Ultra Basketball

According to various reports there was a limited amount of 2007-2008 Fleer Ultra Basketball produced with a blank back. The printing error occurred on a few subsets, specifically the Lucky 13, Premiere, and Legendary 13 subsets.

Upper Deck said that the error occurred on only 200 sheets and was caught by quality control, which probably means that there are going to be very few that make it out into the public.
