Big Wheels Keep On Turning. 1979.

The riverboat, long associated with Cincinnati, is used as a central design element on the pin issued for the 1979 U.S. Figure Skating Championships. In a marvelous feat of engineering, the riverboat glides smoothly along the Ohio River atop a stylized skate blade, with the large paddlewheel pushing it along. After all, it was February when the temperatures in Ohio may have been low enough for the river to freeze over for skating.
