Resident MBC Esquire and dad of future Hall of Famers, John McGrath sent me this picture, of Semi Pro, Independent and Defunct League Shirts that are available at Haight St T shirts. Looks like a lot of the selection that one can get at Ebbets Field Flannels, without the wait.
Check it out if you are interested. Thanks John!
