David Malki, author of the online comic strip Wondermark, has produced this collection of humor entitled "Beards of our Forefathers". For those who do not know his comic, he takes period illustrations and adds captions and dialogue for humerus purposes. And while there are certainly beards to be found within, such as his marginally useful Pocket Guide to Ancestral Beards and Ironic Facial Hair Citation, he focuses very little upon the actual beards of our forefathers.
This is not to say I was disappointed in his book. Assuredly not. Even without beards and mustaches, the the humor is significant.
