(REPOST) David Letterman sign-off - WLWI-TV13 (now WTHR) Indianapolis (1970s) · 6:16pm Oct 18th, 2018
Perhaps one of the most widely-seen videos on my old account (the one that got terminated in February), this came from channel 13's compilation of clips of David Letterman which was posted after he retired from CBS' THE LATE SHOW (the compilation in question is embedded below). Here, Mr. Letterman (that's him!) blows up a cardboard model of WLWI's studios and offices to signify the close of its broadcast day.
