Pathetone Weekly : Cinemagazine
“Pathetone Weekly, the British cinemagazine, ran semi-news blurbs featuring obscure topics that aired from 1930 to 1941. This episode...displayed concept clothing created by American fashion designers detailing what they believed clothing would look like in the year 2000. The ideas ranged from women wearing cantilever heels...to men wearing telephones on their chest.”
Cantilevered heels were patented by Martin Friedmann in 1956.
