The German Olympic Committee, Nationales Olympisches Komitee für Deutschland, were the first Summer Games organisers to elect to change the reverse of the medal. The 1972 design was created by Gerhard Marcks, an artist from the Bauhaus, and features mythological twins Castor and Pollux. Since then the Organising Committee of the host city has been given the freedom of the design of the reverse, with the IOC giving final approval.
