Book excerpt: General Motors styling 1927-1958 walks through the "Harley Earl era" of automotive styling, with research and interviews that go beyond Oldsmobile, Pontiac, Chevrolet, Buick and Cadillac, and into the extravagant dream cars and Motoramas of the '50s. Giant personalities include those who would later leave GM to make names for themselves elsewhere: Frank Hershey, Virgil Exner, Gordon Buehrig and others.
