In 1941, for the sports fan who wanted to listen to the baseball game on a baseball, this All American Five was available. The ball was about nine inches in diameter, and had tuning knob on one side and volume on the other.

The radio bore the “Trophy” name, and as you can see from the handwritten notation, it came from the D.A. Pachter Company, Space 1142, Merchandise Mart, Chicago. The company had a wide selection of novelty items, some of which you can see in this 1950 catalog.

They included a matching bowling ball radio, which you can see here.  A nicely preserved example of the baseball radio can be seen at this link.  The photo above appeared in the October 1941 issue of Popular Mechanics.
