Fauntz parlayed her Olympic success to a career in marketing, modeling, and professional aquatic exhibitions. She became one of the first female athletes to appear on the Wheaties cereal box; she was also one of many celebrities of the time recruited to endorse cigarettes (in her case, Camels) and beer (Falstaff). Jane also appeared as cover girl for "Life" and "Ladies Home Journal". She worked as a model for Saks Fifth Avenue. As a professional diver, Fauntz appeared in exhibitions at the Chicago World's Fair in 1933, where she met future husband Edgar "Eggs" Manske, an All-American football star at Northwestern University; they married in 1936.
