It is simply not physically possible to read a Sergio Aragones book and not chuckle or smile or even guffaw. They’ve proven it with some intensive internet testing, I think I read on some website.
The first volume in Mad Magazine’s Big Book series features nothing but Sergio Aragones, with a bit of assistance by Frank Jacobs on some of the more text-y pieces. It has strips and gags from throughout his long career at the magazine, along with a section of magnified Mad Marginals that came to be be identified with both Aragones and Mad.
You can usually still find this one relatively cheaply on Amazon or eBay, and it is definitely worth the money. Highly recommended!
