Jet and rocket imagery was everywhere in the atomic fifties, and few companies took to it as much as General Motors. For a while their cars had rockets and swept wing jets everywhere, especially at the front. This one's an Oldsmobile Rocket 88. I totally dig the contrails molded into the sheet metal of the hood. You don't see that level of detail anymore.
Olds got an extra rocket at the back, too.
This sporty number's off a Pontiac
This one's a Buick, I think. It also looks more like a torpedo, but whatever.
And finally, a tribute to Northrop's flying wings, courtesy of Pontiac.
