There's a new aspect of heraldry today in the symbols used by the air forces. This is a picture book devoted to this new field, with respect to the American Army Air Force. Introductory material gives some personal and historical data of the first World War and the insignia of the Aero Squadrons, the subsequent rules of design and use; the ramifications and developments in today's war, and tradition in the making. Badges, sleeve patches, schools and training centers, commands and wings, service, staff, reconnaissance, ferry communications, weather, anti-subrarine, and so forth. Complete coverage with some 200 pages of drawings of designs. The market --not only these in the field of aviation, but the boys to whom recognition of such symbols is a mark of true understanding today.
