Oxfam's giant heads of world leaders arrive for G8

Barack Obama's head has arrived in Canada ahead of the G8 and G20 summits -- minus part of his ear.

The giant papier mache likeness of the U.S. president's noggin and the heads of the seven other G8 leaders were unpacked at Oxfam's Toronto offices Monday after being shipped from Germany, where they appeared at UN climate change talks.

Oxfam uses the props for publicity stunts during international meetings, such as the upcoming G8 in Huntsville, Ont., from June 25-26 and the G20 in Toronto from June 26-27.
