Two artists have been playing pretty games with the UK Royal Mail’s automated sorting offices. It seems the machines simply read the colour of stamps to check whether the correct postage has been used, so it doesn’t matter what shape they are. Kim Rugg and John Spurgeon each use proper stamps, only they are cut into tiny pieces to create the art on the envelopes. As long as it’s cancelled, it counts! Rugg creates tentacled monsters (pictured), fireworks and beach scenes, while Spurgeon has a collection of vintage postcards sent with confetti postage called ShakesMyMail.
