I love old colored print advertising. I came across this 1940's Dr. Pepper ad advocating using Dr. Pepper as a meal replacement. The ad is saying if you're hungry and don't have time to eat drinking Dr. Pepper will give you all the nutrients you need. You can drink it at a soda shop, at home or grab one when you get off the plane. During this era companies used this mode of advertising to reach consumers. Not everyone had access to television.
