Wayne used to make them and send them to record stores and friends. I don't think they sold them at the shows. I picked mine up here and there. Gotr my first one (the Lolapalooza) at Sound Exchange about 8 years ago and started looking for them . Picked up a few from Dustin and soem from a friend in OKC. One or two from one of The Lips old roadies. I just lucked out and got them all as far as I knoe. took about 7 years I guess. I heard he only ever made 50 of any of them and most got hung. Finding a "mint" one is even more rare than finding one at all.
