Sunday’s ad is for Pabst Blue Ribbon, from 1949. In the later 1940s, Pabst embarked on a series of ads with celebrity endorsements, photographing star actors, athletes, musicians and other famous people in their homes, enjoying Pabst Blue Ribbon beer. This one features James Montgomery Flagg. He “was an American artist and illustrator. He worked in media ranging from fine art painting to cartooning, but is best remembered for his political posters.” His most famous poster was the of Uncle Sam pointing a finger at you, with text that read “I Want You For U.S. Army,” painted in 1917. “Flagg used a modified version of his own face for Uncle Sam, and veteran Walter Botts provided the pose.”

In the ad, “Monty,” as he was known to his friends, is in his “New York Studio” working on a new painting as an admirer looks on. Perhaps she’s the “Cover girl for a popular magazine” mentioned in the text, and she’s seeing if she likes how he’s drawn her? And if she does, maybe it’s finally time to drink those beers.
