Okay, I've been going through the cover scans which means I can tell which Class comic had Marvel or MLJ(Archie) super heroes in.
But although I can spot the odd character and story from the Timely/Atlas/Marvel eras I'm no expert -Ditko and Kirby worked for other companies so saying "That's Marvel!" because of a Kirby cover....no.
For that reason I am only going to concentrate on the super heroes, which most people seem interested in anyway.
So watch out for these post titles:
Hey, Hipsters -It's Like The MLJ Guys At Class! Groovy.
Make Mine Marvel...At Class!
