UPDATE: I received my copy of this book. Published in French, the book is full of French-specific photos (over two hundred). Most are from WWII, but some are from later years other areas around the world. Besides jeeps, photos of GPAs during the war years appear and, from later years photos, a few military CJ-3As along with a five-star Jeepster.

The author also explores the inscriptions/markings of French WWII jeeps in-depth, but lacking any background in that information, I can’t say how accurate (or not) the information is.

On the downside, the book promotes the phrase “General Purpose” and “Government purpose” as the words behind “GP” in GPW. The book also only recognizes some prototypes, but not others in it’s brief chart of production numbers (pg 16). 

This book is written by Paul Gaujac. It’s a 144 page book that you can purchase on Amazon (I’m sure it is available elsewhere, too).
