Special Notes: All discs of this Style are Canadian. These are also the only Pro-Models with hot stamped cupolas, and are believed to be the earliest tournament disc sporting a hot stamp (rather than a label) commemorating the event. CNE stands for Canadian National Exposition, which hosted the first Canadian Open. Guts and distance were the only events. For more on the event, see this article on the History of Frisbee and Disc Sports in Canada.
