Yes, it was probably one of Harry's sets, but in any case, we always seem to spot that stuff in movies and hit the rewind button to go back and look! Anytime I see an old TV or radio in the background, I stop the movie to get a better look. It ends up pissing off everyone else watching the movie!
I recall doing the same thing while watching
Grumpy Old Men for the first time. There were a couple of old sets in that movie. Seems I remember one of them being turned into a fish tank!
I've always been a fan of the TV show
Bewitched with Elizabeth Montgomery. One day while watching the movie
National Lampoon's Christmas Vacation, i noticed in a shot of the neighborhood that Samantha and Darrin's house was just down the street from the Griswalds. I had to back up the movie to get a better look and verify.
In any case, we spot this stuff in the background. It just goes to show that we still have good eyesight!
