And me too. That project began when I got an assignment from Len Brown to write hundreds of jokes. Researching numerous sources in the Boston Public Library in the winter of 1969-70, plus my own files, I produced a huge manuscript of jokes in many different categories. Then, as I recall, Art Spiegelman and Jay Lynch did roughs adapting those jokes into comic strips and cartoons with balloons while also adding new gags.
Loved these. I think I owned most of the set as a child. Thanks for the link to view the whole set!
