Squirt Soft Drink Promo (1), c1940

Guessing a date here wasn't easy. Squirt was created in 1938, and the ubiquitous kid mascot, ("L'il Squirt") doesn't appear until 1941. All this according to the drink's current producer, which adds that it became established as a mixer in the Fifties.

However, these graphics look more Forties than Fifties to me, so there you are.

Front and middle section of an eight-section foldout. (There was a cut up top that allowed it to sit atop the soda bottle with the arrow pointing down to the label.)
