Ed Emshwiller

Edmund Alexander Emshwiller (February 16, 1925 – July 27, 1990) was an American visual artist notable for his science fiction illustrations and his pioneering experimental films. He usually signed his illustrations as Emsh but sometimes used Ed Emsh, Ed Emsler, Willer and others.[http://www.isfdb.org/cgi-bin/pl.cgi?58587] For June and July (when the novel concluded) he did the covers as Emsh and Willer respectively. He was Willer as illustrator of the novel; Emsh and Ed Alexander for two other July stories.}} Provided by Wikipedia
