This is a Post Card written to me by a friend who visited the expo67 World's Fair in Montreal, Canada.  The front of the post card depicts "The Pavilion Of Germany", which was a lightweight structure with eight steel masts carrying 100,000 square feet of translucent "sky" providing all-weather protection.  The cancelled stamp is 5 cent Canada expo67.  What a wonderful nostalgic piece of history one can own...especially if one is Canadian.
