Fantastic Adventures By Paul Frank

Fantastic Adventures is a series of vintage illustrations by Frank R. Paul. Frank Rudolph Paul (April 18, 1884 - June 29, 1963) was an illustrator of US pulp magazines in the science fiction field. He was born in Vienna, Austria and died in Teaneck, New Jersey. A discovery of Hugo Gernsback (himself an immigrant from Luxembourg), Frank R. Paul was influential in defining what both cover art and interior illustrations in the nascent science fiction pulps of the 1920s looked like.
Paul's work is characterized by dramatic compositions (often involving enormous machines, robots or spaceships), bright or even garish colors, and a limited ability to depict human faces, especially the female ones. His early architectural training is also evident in his work.
