For some unknown reason, Thom Yorke, the lead singer in Radiohead, is on the cover of an Iranian sex manual.

The manual called Marital and Sexual Problems in Men, was spotted in an Iranian bookstore three years by journalist Sobhan Hassanvand. Hassanvand tweeted the image a few days ago.

Yorke isn’t the only known face featured on the sex manual cover.

American writer John Updike, who died in 2009, is also pictured on the front of the book, alongside a third, currently unidentified man.

This isn’t the first time that Yorke’s image has cropped up in an unlikely (but inadvertently hilarious) place.

The website Dangerousminds.net found that Yorke also appears on the Russian sign below, which apparently advertises a product designed to “help you to forget about insomnia, fatigue, skin problems, cold, attention deficit disorder, and headaches”.
