This ad campaign, luring businesses to advertise on TV in Duluth/Superior uses a picture of supporters of the Revolutionary government of Cuba manning a machine gun post overlooking one of the main streets, Zapata Avenue, into the heart of Havana, Jan. 4, 1959.

Honestly, how does comparing the opening of the Seaway to the communist revolution in Cuba get advertising? How does this work?

I’m looking at more relics of the history of media in Duluth, from the Media History Digital Library.
