Just in case anyone feels like spending $250 on a Pyongyang Traffic Woman poster, I found a couple on this site: http://www.dprkcool.com/servlet/the-template/dprkpropagandaart/Page
They sell genuine artwork from North Korea

Propaganda Poster with Traffic Woman - "Let's voluntarily keep traffic orderly!"

Propaganda Poster of a Traffic Policewoman Bidding Farewell to the General, Kim Il Sung:
"Goodbye Father General."
