WNED still used this logo in their sign offs as late as 1993, although they had switched to a different SSB film by that time, and they had also started showing the Canadian anthem, too.
What I find neat about this signoff is that they were still using the word "megacycles" in a sign-off used in 1980. I thought that pretty much went out in the early '70s.
