I want to point out that the male member of the writing team for this book is Noel A. Crowson. I fat-fingered his first name in my earlier reply.
This book uses a number of quotes from Civil War sources detailing the guerrilla shirts and follows that with 1860s photos and drawings of guerrillas wearing several examples of the shirt. The shorter chapters about guerrilla hats, spurs, weapons, and other items also features pictures of many of the models described. The bibliography includes 11 different sources and the book is rich in pictures. It appears to be geared to re-enactors, but there is enough factual detail for others interested in Missouri Civil War guerrillas. I don't recall what I paid, but I was pleasantly surprised at how much I got for my money in this 51-page book. I have all this stuff in other sources, but not in one book.
