Why two sets? Because the 132 cards is printed on 2 sheets with 64 different cards on each sheet so you'd have to do some surgery to make a single complete set. These were not stored great and are wavy, in some places resulting in creases. We have taken close ups of the Maddux cards so you can see how they were affected. Includes a bonus sheet for 3 total sheets 2 and a half sets.
