The Mayor of what, you ask?
The Mayor of Cooperstown, Jeff Katz!
He's also got a few books out, the latest of which, Split Season 1981, I keep meaning to pick up, as '81 is the first (mostly) full season I remember details of, even with my card collection starting in '80.
Jeff had commented on Twitter that he finished his '70 Topps set, which led to me mentioning that I'm closing on it, which led him to mention that he had some extras left over from his set-building, and that turned into a trade, where I sent a pile of vintage football to Jeff, and he sent 26 '70 cards from his stash. This brought me under under 100 cards on '70 Topps, and did so in style. Here's a partial look at the pile I got (just going with the Hall of Famers and All-Stars, as I'm mildly sleep-depped right now).
Thanks for the deal, Jeff, and good luck on '55 Bowman football! (Folks, if you've got '55 Bowman football, he's looking. Get in touch with him!)
