“Marcus Keef was a British photographer who in the early ’70s became known for his moody, atmospheric, and often creepy album cover art. He is most closely associated with the work he did for the Vertigo spiral label, although he was contracted by other labels as well, such as Neon, and Nepentha; and some of the albums were released in America under the Mercury label. … his real name was Keith MacMillan, but he used the pseudonym for his work as photographer, possibly to avoid confusion with another famous photographer with the same name.” — Lomography
