Here are just a few of the limited run Topps cards I have aquired of our favorite team, I have several others. The are all variants of essentially the same two standard base cards. most are limited to print runs of 50, 25, 10, 5 and then there is the rare 1 of 1 printing plate (bottom row, second from the left)
I'll pick up additional copies whenever I see them, and maybe be able to complete the full runs of some of the X/5. x/10, x/25 and x/50 cards.
Topps is releasing Topps MLS Chrome soon, so there might be additional NYC FC Cards in that set as well.
