'70 Zenith 12" tube type B&W

[radiotvnut]

I picked up this animal from a member on ARF. I think it's a model A1331; but, can't be certain because the model tag is messed up. I think I remember Doug H. telling me a long time ago what years the model suffixes matched with and I think "A" was 1970. This is a fully tube type set and there's no mention of "Taiwan" on the back (big plus). All I did to this was clean the VHF tuner, user controls, and tube sockets. The only thing wrong with it is a very touchy UHF tuner. I'm not too worried about that since UHF is about to be history in my area. This thing still had all original Zenith tubes and I suspect that I'm the only person that's been inside this TV.

Oh yeah, for five extra points, tell me what TV program is displayed on the screen. There are several clues in the pictures.
