Not sure if this is aimed at kids or big kids. Basically, if you like old games machines, you’ll probably appreciate the retro gaming wallcovering by Murals Wallpaper.
As you can see, thus is a design packed with vintage controllers and handhelds. What you can’t see is the number of colour variations on offer. Let’s just say there are a lot and almost certainly one that matches up with your room requirements.
All the designs are made-to-order and custom sized according to your wall dimensions. £25 per square metre is the guide price.
