The Leopard from Lime Street
The Leopard from Lime Street is a comic strip appearing in the British comic Buster from 1976 to 1985. Written by Tom Tully, it was drawn in a 'realistic' comic style by Mike Western and Eric Bradbury, much like Marvel Comics's Spider-Man comic (to which it bears numerous similarities), in direct contrast to the stylized cartoony style of the rest of Buster.
