Star Wars Schmidt POG
Set of 70 (1-70)
There are 25 in this set of 70 that have foil backgrounds. Each of these 25 is available with 4 different foil patterns. Therefore, the complete set (with all 4 backgrounds for all 25 Tazos) would be 145 (45 normal + 25*4 foils).
There is a checklist for this series, but the names of the POG listed on the Checklist don't seem to match up with the images shown on the POGs themselves.
