Granted you'll need to be a fan of the band to full appreciate these, but if you are, The Beatles wall murals at Photowall are pretty spectacular.
Helpfully, the site has computer generated images of each wallpaper design in various rooms, so you can see how it might look in different settings, although noticeable all of these rooms lean towards minimalism. Pictured here is the design they simply call Retro – Orange, which I’m sure is pretty similar to a pair of curtains we had back in the Seventies, so have a soft spot for (although I think I might tire of it quickly looking at it every day). Other designs include concentric hexagons, curved corners squares, diamond shapes and other psychedelic styles, all in bright or strong colours.
Whereas most wallpaper is sold by the roll, Photowall sells its designs by the square metre so you can order exactly how much you need for your wall. Designs in the retro collection cost either Euros 21 per m² or Euros 24 per m². Visit the Photowall website to see the whole collection.
