Cal Ripken, Jr Hall of Fame display plaque with autographed baseball. I purchased the plaque in Cooperstown right after his induction into the Hall of Fame in 2007. The baseball was signed at a spring training game in 1996 in FL. The signature is not authenticated....I was there when he signed it. Unique gift for the Oriole fan. You can find other signed baseballs, but not in a commemorative plaque like this. This is from my personal collection that has been safely stored out of direct sunlight in a controlled environment. The plaque measures 15" x 23" and is made of solid oak. Hooks on the back allow for quickly hanging on the wall. You will not be disappointed.
