Surprised this hasn't sold yet. Wish I had the room for it.
Nearly certain this is a promo piece for Milwaukee writer Jos J Krueger's 1946 book about the World Series. Book was self-published in Milwaukee as well. And those exact photos are in there. May just have a one-of-a-kind item.
Photos include: Christy Mathewson, Honus Wagner, Johnny Evers, Tris Speaker, Ty Cobb, Babe Ruth, Mickey Cochrane, Connie Mack, Lefty Gomez, Lou Gehrig, and more.
