The adverts for the Commodore 64 computer on magazines used Kabel Black in all caps for titles. Notably, even the computer’s name was rendered in Kabel Black sometimes—apparently mostly around 1985—rather than using the logo in Eurostile. I can find no evidence that this Kabel Black rendering of the name was ever an official logo of the computer.
The references to “www.commodore.ca” in each image were inserted by their source website as watermarks and are not part of the original adverts.
