A number of posters placed around Europe could be the work of Radiohead, if fan speculation is to be believed.
On May 21st the band's seminal 'OK Computer' album turns 20 years old, leaving fans to speculate about a possible anniversary event.
A series of posters have appeared around Europe, and seem to tie in with the album's message while also being emblazoned with the dates '1997 – 2017'.
As yet, there's nothing to tie it to Radiohead except… illustrator Stanley Donwood – who has worked closely with the band – has placed some teasers on Instagram.
