This volume contains all of the Napoleonic plates that were first issued individually. It is a very helpful resource for French uniforms-accurate, highly detailed, and meticulously researched. It is helpful to collect the plates individually as they are in a larger format, but sometimes they are difficult to find.

I have a complete set of the Napoleonic plates which took me about ten years to compile. I prefer them to the book.
