I had wanted to post this front page on September 13, the 40th anniversary of the demise of Chicago Today, but I couldn't remember where I had stored my copy.
For a time, the Tribune continued publishing a "red streak" edition in the afternoon. Its news was updated from the morning edition, but its features were not. It's hard to imagine why the publishers thought an afternoon paper with identical features to the morning edition would sell better than an afternoon paper with its own features.
You can read a more complete history of the Chicago American and Chicago Today at the Chicagology site here.
