I'll be making a (seemingly rare) jaunt down to Chicago this weekend to help a friend vend her vintage here: https://www.vintagegaragechicago.com...-garage-april/
Looks to be a good show, although I've never been.
If you're around, look for the ReWare Vintage booth (won't know our spot number until we load in Sunday).
ReWare specializes in vintage band shirts and apparel.
