The artist's illustrations of scantily-clad women surviving in outer space served as an inspiration for Princess Leia's slave-girl outfit in "Return of the Jedi", even its color and cut, and Madonna's conical brass brassiere. Bergey's science fiction covers, sometimes described as "Bim, BEM, Bum," usually featured a woman being menaced by a Bug-Eyed Monster, alien, or robot, with an heroic male astronaut coming to her assistance. Bikini-tops worn by Bergey girls often resembled coppery metal, giving rise to the phrase "the girl in the brass bra," used in reference to this sort of art. Visionaries in TV and film have been influenced by Bergey's work; Gene Roddenberry, for example, provided his production designer for "Star Trek" with examples of Bergey's futuristic pulp covers.
