Postcard from Expo 67, held from April 28 to October 27, 1967 in Montreal, Quebec, Canada. Nice red and blue design showing the Canadian Pavilion, produced by The Queen's Printer in Ottawa. Posted with a 4 cent stamp, with a brief message to friends at Acme Markets in Hanover, Pennsylvania. Clean, with minor bumping at the corners. Overall, the card is in great shape.
