Thanks go to Greg Long for sending along what is undoubtedly a rare poster from the era when Citroëns were sold in Canada.  Judging by the door handles it would from 1969 or 1970.  The Canadian spec D models at that time had the European turning headlights and front turn signals mounted above the bumper.  The house in the top photo probably indicates it was shot in Montreal, most likely on Mount Royal.

Has anybody else come across these photos prior to now?
