Canada. This is an abstract aluminium set purchased during the Olympiad of Haifa in 1976. The set served as shop window material in a photo shop. It was owned by an Israeli aircraft captain, who was responsible for the purchase of aircraft. It was said that it was a promotional gift of a Canadian aircraft manufacturer. This set has similarities with the well known set by Austin Enterprises 1962 chess set, but our set could be one of a kind.
