Obama and McCain - races reversed
An image has been released of US presidential candidates Barack Obama and John McCain with their races reversed.
The striking picture of a white Obama and a black McCain is intended to challenge race as an issue in the US election.
Organiser say it's intended to remind US voters to: "Let the issues be the issue", as they go to the polls on election day.
Tor Myhren, chief creative officer of global ad agency Grey New York's, said: "This is a non-partisan image. We wanted to address the race issue straight on.
"And it cuts both ways. If you're hopping on either candidate's bandwagon solely due to the colour of their skin, you're voting for the wrong reasons."
The image has been picked up by several public high schools in New York, Denver and other US cities. A lesson plan has been built around it, and it is being used as a discussion piece for students.
