This is an English-language book or magazine about aircraft and/or aircraft modeling.
This is the first title in the series dedicated to aircraft and history of JG 51 (Fighter Squadron 51) in WW2. Text is in English and Polish. Filled with period photos and color profile drawings of the unit's aircraft. Plus, includes a complimentary bookmark with color chips for RLM 68 Lichtolivegreun and RLM 77 Lichtgrau. Very nice!
