It's a World World, World, World, MAD #19
Note: Most MAD books have multiple cover variations. If a variation is known, I will have it listed here. If it is part of my collection you will see a cover scan. If I am still searching for that variation, you will see a coming soon picture. If you are aware of another variation that is not listed here...PLEASE email me with the information and preferably a cover scan so I can update this list. I would like to see this list as complete as possible for collectors to use as a reference guide.
