Okay, maybe you guys could help me pinpoint the origin of my mystery Holiday Special?

Like I said, there appears to be no station IDs of any kind. The first ad break comes about 19 mins. in, and features two commercials only; One for General Motors ("People building transportation to serve people"), and then one for the "Trailtracker" car toy.

The ads seem to match the main programme in general image quality (reddish tint, uniform bluriness etc.) so I believe they are part of the actual, original recording.

This is identical to the one I have with the Rifftrax commentary, actually, but the image on the Rifftrax seems to be darker, and with more neutral colors. Maybe the same source with some post colour tweaking?

So, where are these from? Ring any bells?

(The other ones I have are the KCMO and WMAR2.)

SKot, I'm a longtime admirer of your Holiday Special site. You should get a book out. This info needs to be organized and preserved.
