1954 General Motors Motorama Event Token Grades GEM Unc. The General Motors Motorama was an auto show staged by GM from 1949 to 1961. These automobile extravaganzas were designed to whet public appetite and boost automobile sales with displays of fancy prototypes, concept vehicles and other special or halo models. Motorama grew out of Alfred P. Sloan's yearly industrial luncheons at New York City's Waldorf Astoria, beginning in 1931. They were almost invariably held in conjunction with the New York Auto Show, that for many years was held traditionally in the first week of January.
