Here is a concept that I came up with for a "Dos A Cero" shirt. Of course, If I printed it, the back would not have the snake and US crest on the back. I just thought it would look super cool like that. But, if there is any interest, I'll see if I can get a couple of these printed at a decent price. Let me know what you think.
Nice design. But you're neglecting the one that started it all: July 5, 1991 in Los Angeles, Gold Cup Semifinal.
I tried to PM you, but you don't accept PM's. If possible, you may want to include space (or something to separate the games), because it looks like it may run together. Perhaps it won't be as "scrunched" on a shirt.
You also need to contact International Sports Images in order to license the image of Landon Donovan. That photo you've taken that image from is one of theirs. I'm sure they'll be very reasonable given that they are fans of the game.
