This is a book or magazine about tanks/AFVs and/or military modeling.
From the Ampersand website:
The Panzer II was Germany’s first cannon-armed tank in the post-World War I era. Designed and initially produced under the code name of 100-horsepower Farm Tractor, owing to the restrictions of the Treaty of Versailles, the Panzer II remained in production, and in the field, well after it had been surpassed by better engineered, more heavily armed and armored vehicles, and indeed played a key part in the early victories achieved by the Blitzkrieg.
The third in our expanded Visual History series features nearly 200 scarce wartime photos, illuminated by detailed captions. Coverage includes the Pz.Kpfw. II Ausf. A; Pz.Kpfw. II Ausf. B; Pz.Kpfw. II Ausf. c and A-C early; Pz.Kpfw. II Ausf. c, A, B, C modified Pz.Kpfw. II Ausf. D; Pz.Kpfw. II (F) Ausf. A & B; Pz.Kpfw. II Ausf. F; Pz.Kpfw. II Ausf. G; Pz.Kpfw. II Ausf. J and the Pz.Kpfw. II “Lynx.” All of the photos have been carefully selected to showcase the many details of the variants. Many "Panzer rarities" will be found within the 168-pages of this hardbound volume.
