About 15 years ago I bought the sign on the left in the photo below. It's made of a pegboard type wood (without the holes) and measures about 18 by 32 inches.
The "Welcome Home Champion" and "First Game - Detroit / Fri. - April 22" dates it to 1949. I've always thought these were made to hang at either the ticket windows at Cleveland Stadium or at retailers that sold Indians tickets (or both) during the weeks leading up to the season when the team was in spring training. This has been one of my favorite pieces, and until today I had never seen or heard of another.
I did a double-take today when I saw the one on the right. Not until I got it home did I realize that the one I already had has Chief Wahoo looking to his left, as opposed to the new one, which has him looking right. Nice pair of bookends -- at least in my world.
