Note that the 1st Predator versus Robot Fighter promo is numbered 3, but is promo for comic #1 and the 2nd Robot Fighter... is numbered 4, a promo for comic #2.  

Zero Month is a dealer 4-1/2 x 3-1/4" card that opens up to show the comics of the DC comics crossover event.

I will consider offers and will combine shipping if warranted.  All will ship in a card sleeve inserted into a toploader, placed in a team bag with protection from 2 common cards on either side, with a small piece of painting tape to secure it within an eBay standard envelope.  

I will consider offers - you'll have to message me with them.
