This “moving picture puzzle” challenges the baseball fan to slide these jumbled square’s into a familiar home plate scenario - the strike! This antique, turn-of-the-century puzzler is still pleasing to the eye, and comes with the complete box and pieces (litho paper on wood) intact. Measures roughly 5 ¼ x 5 ¼”. “Do Not Lift The Pieces.” The only one known to be in existence.
