Concerning Expo 67 in Montreal: We did not have the week, or month, or entire season books. We bought one day tickets at the Oratory gift shop. They were $2.25 each. At the gate they cost $2.50 per day. It was about 3 inches by 2 inches with printing on the front and back along with the "Man and His World" symbol on it. The entire ticket was taken from us when we entered. When we were leaving we could have our hand stamped and return that same day at no charge. Anyway that is how I remember it - over 50 years ago! Hope that helps some.
