1. It only become acceptable for American men to go topless at the beach in 1935. Jantzen almost immediately started featuring bare-chested hunks in their ads. 2. "Skip the flattery darling, my Jantzen takes care of that." 3. Sexual TENSION. 4. Running in heels on the beach. Look's like she's stepping on his toes. 5. From 1939. This one is illustrated by Pete Hawley, who started taking over the work as we moved into the 1940s. Love the one guy pushing the other guy's head.
