An original Rechenaufgaben Luftwaffe (Arithmetic Workbook) dated 1942.
This booklet was used for mathematical instruction during the war years and is a fascinating example of how even military-related themes were integrated into the German educational system of the time.
 
What makes this example especially desirable is the crisp, well-preserved stamp featuring the Hakenkreuz (swastika)from the Knabenschule an der Ritterhuder Strasse in Bremen (see photo) – a boys' school where this workbook was once in active use. The stamp adds a unique provenance and historical context to the item.
 
The workbook contains a series of Luftwaffe-related arithmetic problems and illustrations, offering insight into the mindset and structure of wartime education in Nazi Germany. It is in good condition for its age, with all pages intact and legible.
