Teenage Mutant Ninja Turtles TMNT Fan Club 2013 SDCC 5x8 art card set

Partial set (4 of 6) different Teenage Mutant Ninja Turtles Fan Club 5x8 inch artwork promo cards distributed by Nickelodeon at 2013 San Diego Comic-Con. The backs of the cards are the same. 3 random cards were given to each person so making sets was difficult. The cards were rubber banded together by the booth employees so the cards have minor handling flaws and wear.
