Rare original pattern book Lehrbuch über das Carré-System von Rudolf Maurer

Rare original pattern book Lehrbuch über das Carré-System von Rudolf Maurer. This book describes how to size, draw, cut, sew and finish clothing and uniforms. Whilst this book is mostly about the cutting of civilian clothing; it describes the measuring system the Germans used and has a bunch of military patterns in the back of the book. If one would like to study the manufacture and cut of uniforms; this would be a nice base.
