It's for a New York City location of Marinello Schools of Beauty, which existed from 1905 to 2016.
This was mailed to Don Charles in early November 1953, when U.S. president Dwight D. Eisenhower was likely preparing the Atoms for Peace address he would give within weeks at the United Nations.
On the addressed side of the advertisement, a robot is styling a woman's hair and the cliffhanger caption states: "if a ROBOT could style hair..."
The punchline to that statement must be on a different part of the advertisement. On the reverse side, however, we get this pitch: "You are invited — to participate in the Marinello plan to lick your operator shortage. Select future operators from among your friends, relatives, customers. Send them to us."
And it won't surprise you to learn that this is the first-ever appearance on the internet of the phrase: "the Marinello plan to lick your operator shortage."
Because we're all about remembering — and making — history here on Papergreat.
