Remember Expo 67? Me, neither. It was held in Montreal, where you could have visited the Brewer's Pavilion and sampled, perhaps, some Black Label beer. The tiny blurb on the back side shows that the copyright (1963) belongs to Compagnie candienne de L'Exposition universalle de 1967, not to Black Label. Therefore, I'm assuming that any exhibitor could have used this format for their own giveaway.
This measures 4.75 inches square and is in fair shape. This wheel gives the routes and mileage to the Expo from various cities, both in and outside of Canada. Black Label beer is still produced today. "A Canadian product known throughout the world." If you say so.
