I remember buying the new year's set quite often from Renata Galasso. You could get those great special sets that they always included with the new sets. I also remember getting many commons from Bill Henderson at several of the bigger midwest shows. He always had such a giant selection at good prices. But one place I used to order from all the time was Wholesale Cards Co. in Georgetown, Conn. run by Bruce Yeko. I would always send a list with alternates, include a check and sit back and wait to see what I got. I still have the last catalog I ordered from. I got a 1967 Topps series two for $7.95, a 1960 Fleer set for $19.95, and 1964 Topps Giants for $4.95.
Those were the days! I also remember later on winning many nice mail auction items from Johnny Adams Jr. Is he still around?
