Visitors to General Motors' "Highways and Horizons" pavilion at the 1939-40 New York World's Fair came away awed by a vision of the future. The work of renowned designer Norman Bel Geddes, GM's "Futurama" exhibit foretold the communities and transportation systems of 1960, many of which came to pass. Sharing top billing with the Futurama and Previews of Progress, however, was the "'Glass' Car - The first full-sized transparent car ever made in America."

On the chassis of a 1939 Pontiac Deluxe Six, GM collaborated with Rohm & Haas, the chemical company that had recently developed Plexiglas. The world's first transparent acrylic sheet product, Plexiglas was a serendipitous discovery arising from Rohm & Haas' work with laminated safety glass. Using drawings for the Pontiac four-door Touring Sedan, Rohm & Haas constructed an exact replica body using Plexiglas in place of the outer sheet-metal.
