Many of us grew up with the tasty and chocolatey All-American Yoo-hoo, and it's really interesting that it originated from our neighbor, New Jersey, in the 1920's. Later, in the '50's and '60's, the New York Yankees and Yogi Berra officially sponsored Yoo-hoo. This advertisement promotes Yoo-hoo as a "High Protein" and chocolate "Energy" drink, with a smiling Berra saying, "big energy boost!" in a speech bubble. The ad, on shiny cardboard stock, measures 11 x 17", and has been signed by Yogi in blue Sharpie. Guess it was considered the early version of Gatorade...
