German artist Thitz (born 1962) puts a new spin on the tradition of the artist on the Grand Tour: he paints city scenes upon paper bags scavenged in the places he visits. The bags are opened out flat for maximum coverage, and the paintings are executed with acrylics, in messy, busy, George Grosz-esque delineations of bird's-eye views or individual landmarks (the Manhattan bridge, Chabola City Tower).
