Overview
A complete set of four vintage Tupperware footed dessert or ice cream bowls in semi-translucent frosted polyethylene, accompanied by their original fitting snap-on lids (mold #733-20). Designed for prep, serving, and storage, these versatile pedestal cups are icons of late mid-century practical homeware.
Story
In 1946, Earl Tupper purified black polyethylene waste to invent indestructible homeware. These clever pedestals kept ice cream insulated and doubled as airtight storage cups.
Maker / Origin
Founded by chemist Earl Tupper in Massachusetts, Tupperware revolutionized kitchen storage with its patented airtight 'burping' seal. The brand achieved legendary status largely through Brownie Wise, who created the revolutionary home-party marketing model in the 1950s.
Condition & Value
Very good vintage condition with clear, clean frosted surfaces and no visible warping, cracking, or severe discoloration. Well-preserved seals and clear markings support the upper end of value for standard sets.
