Bruce Lee and Karate was REALLY big in the mid-seventies. Like, HUGE! Karate magazines littered newsstands, knock-off B movies were being imported by the boat load, Men were foolishly wearing “Hai Karate”… and mail-order companies popped up EVERYWHERE – selling the “secrets” of Karate. Here’s some really great ads from that time – I especially love the “Death Touch” one.
