Stuff that just flies out of the booth. Old advertising with great color and graphics. Tins and especially signs. Universal monsters, pre-1970 Disneyland stuff, Slot Cars and Hot Wheels. Old sports memorabilia especially Baseball. Trophies, equipment, photos, toys ect. Being in CA, any vintage skateboards or surfing stuff. Classic vehicle toys. Especially motorcycles and house trailers. I am always surprised what people pick up and buy.
Comic book wise, a little of everything including western and Dells. The flipper kids drift in asking for “keys” and hoping for garage sale prices. But a lot of people just looking for readers from their youth. I don’t usually bring much if any in the way of big keys or nice GA unless someone I think might actually buy it asks me. I sell a lot of affordable comics, MADS and pulps. Me and my partner are usually the only ones to have any of this stuff out there. Most of my customers are mostly looking for the other stuff so that is primarily what I bring.
