WXNE-TV 1977? Commercials (60fps)

Hope everyone is having a good week so far and staying cool in this heat wave! 🎉 This is a betamax tape from my collection I recently digitized. I think it might possibly be from 1977? Which would make this the oldest tape I have found thus far. It consists of commercials and bumpers that aired during Voyage to the Bottom of the Sea, Enjoy! 🙂
