2002 NFL 3-D cereal card premiums
These little beauties are pretty hard to find. The fronts have a dual 3-D image similar to the Sportflix concept but instead of showing simulated motion - these show a second player. On the backs they have a brief statistic and description of both players pictured on the front. Below are the 4 examples available. Please note that I am still trying to locate secondary player images of some. I will update this as they become available.
