“Armless Wonder” Charles B. Tripp and “Legless Wonder” Eli Bowen share a bicycle, from a publicity shoot in the late 19th century.

Each man spent more than 50 years in the circus world — Tripp could write, paint, cut paper, and do carpentry with his feet, and Bowen trained himself to tumble and do stunts on a long pole. But apart from this photo, there’s no clear evidence that the two worked as a team.
