It's difficult to see from the cropped photograph that the tin-shack houses depicted in the foreground of this 430x140x16mm chipboard painting have a 3D appearance. They're actually made from discarded aluminium soda cans!
We bought this piece of art today for R100 (approximately 10 Euros); the artist was selling his work at traffic lights on the Newlands part of the M3, at the foot of Table Mountain. Framed it'll look absolutely stunning.
