Just picked up this one.
The Cosmopolitan Magazine Section of the Duluth News-Tribune, July 29 1956.
Cover art by Al Taliaferro. The interior features special artwork by Walt Kelly, Chic Young, Al Capp and others. I wonder how many of these that have survived?
PS. The image above is pretty similar to this one from 1954.

And it just re-appeared as a "new" cover in Holland. (Thanks, Gerben!)
