1946-1955. Single-sided porcelain (SSP). Raised edge. This thermometer uses the "You're Safe...and You Know it" slogan, which was first introduced by Prestone in 1940. The "You're Safe" campaign was the company's primary emotional "peace of mind" advertising hook, an important premise during the turmoil of WWII. Production of these thermometers ceased during WWII, then started in 1946 when production of porcelain signs exploded. Around 1955, the slogan and "You're Safe" campaign began to disappear in favour of more modern themed campaigns. All items are guaranteed authentic by Miller & Miller Auctions.
