"The Grande Prêmio da Cidade de Rio de Janeiro was held during the 30's on the infamous 11.16km long Gavea track. Known locally as Trampolin do Diablo ("The devil's spring board") the track followed the coast on the edge of a 30 m high cliff and returned to Gavea up in the mountains where it featured a series of hairpins in hazardous terrain"
The trailing Auto Union in this photo is driven by Hans Stuck.
