Last weekend, I picked up some original cartoons by Victor Vashi at a flea market. These were originally done for the Plumbers Journal. The bookseller who had them wrote a note saying Vashi was the author of Red Primer for Children and Diplomats, Viewpoint Books, 1967 and illustrated the Handbook of Humor by Famous Politicians by Stephen Skubik.
Here's scans of all the cartoons, only a few of which still have their captions.
