WW2 German Army reference book - Portuguese military 1941

Softcover, German military reference pocket book printed by the German Army High Command (Generalstab des Heeres) in May 1941. The book measures 15cm x 10.5cm. 73 pages of text and images describing the organization, armament, equipment, uniforms, rank insignia and defensive tactics of the Portuguese armed forces. 11 pages of colourized images of rank insignia and uniforms. There is an attached foldout map that depicts Portugal and its colonies, as well as the disposition of its armed forces. The reverse of the front cover has two Wehrmacht property stamps on it, both of which have been blacked out. Interesting WW2-era German army reference book, part of a series of booklets given out to German officers in order for them to familiarize themselves with the militaries of Europe. These books are hard to come by, I’ve been collecting them for several years. In very good condition, see photos for details.
