Kit-Kat 5" TV

[packrat79]

This is an odd little set I found awhile ago, it appears to be something Kit-Kat was selling or giving away as a promotion. It's a 5" B&W TV in a transparent red plastic case, it operates from 12VDC or 8 "D" batteries. It's made in China so it can't be very old. It has the Kit-Kat logo engraved on the back, as well as printed on a sticker. I think it has a built-in AM/FM radio as well. I can't seem to find any info on it at all.... would this be something rare and perhaps valuable?
