WJZ Channel 13 - "We Love IDs Too!" (On-Screen ID, 1983)
Here's one more example not from Chicago TV but still interesting to show the differences in stations presentations' of The Day After (an ABC Theater telemovie about the effects of a full-scale nuclear attack on the United States).
WLS-TV did not have an on-screen station ID for the entirety of the movie. However, WJZ Channel 13 in Baltimore, Maryland did. I don't have the entire broadcast to see how many there were, but this is at least one example.
This aired on local Baltimore TV Sunday, November 20th 1983.
