It was during the time when cars were worshipped and driving was a popular leisure activity. The 1950s brought us cars that were longer, leaner and more aerodynamic. They also sported fins—BIG ones.

After about a decade the fad died down but not before one more set of tailfins would add to the tailfin iconography: those of the Batmobile.
