German-born artist and musician Klaus Voorman was a longtime friend of the Beatles, and an obvious choice to draw the Revolver cover. The group played him their new track "Tomorrow Never Knows" before he sketched his first draft. "They were being so avant-grarde," Voorman has said. "I thought the cover has to do the same thing. How far can I go? How surreal and strange can it be?"
He asked the Beatles to give him old photos of themselves, and he pasted some of them onto his own drawings. He had trouble with George Harrison's face, so he pasted newspaper photos of eyes and lips onto it. For many years Voorman worried that the original was lost – but he claims to have recently tracked it down. "I'm not going to tell you where!" he said. "It's well kept and looked after and I'm happy about that."
