Seems like an odd item to have in a sports auction. The book is all about stamp collecting with a copy of the 1918 stamp immortalized in the story and is from "Your friend Jack Armstorng, the All American Boy" but the back cover of the booklet brings us into more familiar territory with a Wheaties ad covered with the photos of athlete endorsers including Chuck Klein, Pepper Martin, Babe Didrickson, Red Grange and Lou Gehrig. The envelope shows some wear but everything else is in amaing condition. Not something you find every day, and certainly not as complete as this example!
