Tupperware "Wonderlier" Bowls, circa 1954

In the 1950s, plastic became indispensable--especially in products for the home. Foremost were Tupperware's "Wonderlier" bowls--lightweight, flexible, and unbreakable, with a patented air-tight seal to keep foods fresher longer. Tupperware was more than just a substitute for older materials, it offered qualities previously unattainable. Even Tupperware's marketing method was innovative--sold only at home parties given by a hostess for friends and family.
