In case you haven't noticed, I watch Bewitched quite often!
Looks like Sam and Darrin have moved up to a color set here. Well, more like Darrin moved INTO a color set! Got zapped in there by some witch that Endora knew from "centuries" ago.
Hard to tell, but I think this one is a Zenith as well as the previous B&W set I posted. Dick York played Darrin till 1969, so I would guess this to be a 68 or 69 model Zenith.
