Sir Face Graphics Retro Wall Decals
Simpler, but still just as retro cool is the retro radio sticker. This one just consists of two parts, the radio unit and the music speech bubble, which personally I'd probably leave off. All of the stickers are available in a choice of 30 colours and custom sizes can also be requested. They also give you a spare to sticker to test - ideal if you tend to be a bit clumsy.
Plus they are very reasonably priced - the radio costs £13.20 and the television £19.20. Visit the Sir Face Graphics website for full details.
