This is a WWII German Wochenspruch (propaganda miniposter). It dates to the second week of 1939.
These “Wochensprucher” were official by the NSDAP published little propagandaposters, that could because of their small sizes easily be hung up in houses (e.g. in the kitchen), but also in public buildings, et cetera.
The here offered Wochenspruch is a very rare one and because of its design very desirable.
The dimensions of the Wochenspruch are approximately 35 x 24 centimeters.
In very good condition.
