Dave...Still reading and enjoying the project.
Regarding '52 High numbers. Two more regions that can be added. A few collections have turned up in Western Canada (Vancouver area) and one area that Teddy Z forgot. About 20 years ago, Ted was visiting me and went with me on a call where I purchased a full set of '52 Topps from the original collector. He collected the set while living near Chicago in 1952. I've never found an original collector that bought '52 High numbers (out of packs) in the SF Bay Area....Mark
