Jiu Jitsu adverts in Chicago in 1904

This advert is from the Chicago Tribune classified section, 1904, 35 years before Count Dante was born in 1939 and 64 years before his World's Deadliest Fighting Secrets was published Asian martial arts were already being touted as a self defense secret weapon.

By the time John Timothy Keehan is born in Chicago in 1939, jiu jitsu is almost a common word, used in contemporary speech and denoted awesome powers to disarm, wrap-up and break.
