I like this idea I don't really care for the "surprise" aspect as one may end up with dups (I have a lot of dup modern Cubs). Over the years, when I post a trade of Cubs I am looking for, I have had people just send me a card or two as a freebie. I have done the same to people looking for cards. I am primarily a vintage Cubs guy but have a few Bulls and Blackhawks. My modern Cubs I get via the Box Breaks on various sites and I have a friend who sends me his dup Cubs. I love oddball and have a lot of that also so unless there is a regional Chicago Cub or Bear oddball, I also don't need anything in return.
So Mike, afraid I can't help with Tony Parker. Calsp3 - Carlton - again, since I don't do modern have no help in that regard but do have a 75 Hostess Aaron in VG (no creases).
