KTCA Channel 2 PBS - Last Sign-Off of the 1980s (or the first of the 1990s)

As somewhat of a public TV junkie in the 80s and 90s, I have lots of VHS tapes filled with programming from that era. While combing through the tapes, I found what turned out to be the last sign-off for the 1980s, aired on New Year's Eve, after a re-broadcast of 1988's Land Of Loons 2 comedy special. I suppose technically this is the first sign-off of the 1990s, since this occurred after midnight...probably around 1am, when KTCA usually signed off for the night. (Note the date at the end of the signoff.) Anyway, this is a glimpse of an era when public TV stations didn't run for 24 hours.
