This ad for Crest toothpaste was the back cover for the April 1959 edition of Good Housekeeping. Hiring Normal Rockwell as your illustrator for an ad campaign would have been a big deal in the mid-century. Rockwell was a celebrity whose name was known by all. His work for Crest included a series of illustrations showing children holding a “No Cavities” card. Each ad had the same tagline.
Here is another Normal Rockwell Crest ad from my collection. This one is showing a Junior High Aged girl. She is also the proud recipient of the “No Cavities” card. It is from the October 1958 edition of Good Housekeeping.
