KMOS

Background
KMOS is a PBS affiliate from Sedalia/Warrensburg, Missouri (part of the Columbia/Jefferson City market)

1st (known) Logo (1970s-1980s)
Logo: We see what looks like a brown river on a black background (could be due to film quality). "KMOS-TV 6" (with the "6" in a very abstract font) and "Sedalia/Warrensburg" are seen below.

Technique: None, it's still.

Music/Sounds: None.

Availability: Seen as a station ID.

Legacy: The logo's quality looks poor.
