Picked up a few more cards for my Animated Batman collection: two more prototype cards and one insert card.
1993 Topps Batman: The Animated Series, Series I
NNO Fiery Background
NNO Batman Fighting Man-Bat
The back of both cards is the same:
I now have the three regular-size prototype cards from Series I and II.
I also picked up this thermal card:
1996 Skybox Adventures of Batman & Robin T1
The "thermality" of the card is pretty worn off so it's easy to see that the villians hiding in the darkness are non other than Catwoman and Riddler.
