Would this be the Emerald City ComicCon? Because I was at that one over the weekend. I picked up...
Deadpool #s 6, 11, and 68 (which I then got signed by Gail Simone)
Justice League Europe 1-5. (I got all but #2 for twenty-five cents each.)
JLI 4, 21, and 22
Thunderbolts 16 (which Kurt Busiek, as he was signing it for me, called the "Special fat girl cover.") and 57.
New Thunderbolts #1
aaaand the entire "Unresolved" arc of Gotham Central. Can't quite remember what issues those actually were.
Got a decent amount of stuff for twenty bucks, really.
