Earl S. Tupper began experimenting with plastics in 1938 and by 1945 had produced his first tumbler. Tupperware Home Parties was formed in 1951 to sell products through dealers using a party plan. These beautiful salad tongs are in unused condition. The "service-talented" salad tongs "separate for mixing". The tongs are marked "Tupperware". The box, dated 1958, is in good condition with minor tears on both ends of the box. The tongs and box are pictured in "Spiffy Kitchen Collectibles" by Brian S. Alexander.
