The Pontiac logo proves to be a very good logo as it has not changed significantly since its conception more than 60 years ago when in 1957 General Motors ran a design contest for a new Pontiac logo at the Beverly Hills Art Center School of Design.
Phil Gianopulos won the contest with his arrow shaped submission for the Pontiac emblem. The logo hasn't changed a lot compared to Gianlopulos' first sketch.
