Welcome to a special topic in Postal History Sunday! This time we'll take a virtual trip to Chicago for the Great American Stamp Show hosted by the American Philatelic Society. But, before I get into it too deep let me first remind you to put those troubles in the laundry with your dirty socks. If we're all lucky, the troubles will disappear with all of the missing socks that have resulted in a drawer full of single, unmatched footwear. If it doesn't work, we'll always say it SHOULD have!
