Traditionally the pre-Revolutionary War song was sung by British military officers to mock the disheveled, and disorganized colonial "Yankees". The term "doodle" meant simpleton and the
verse implied a group so unsophisticated that sticking a feather in a cap, would replace the stylish macaroni wig and elevate them to the height of fashion.
Contrarily, this charming and patriotic ad, illustrated by Pete Hawley, proclaimed a new American custom. "Look wonderful, feel wonderful, do wonderful things in a Jantzen foundation...with the famous Jantzen swimsuit allure...with freedom."
