This is a miniature Luftschutz booklet, from the very rare Luftschutz Jugendbücherei. this is number 5.
I believe this minibooklet was issued under the flag of the National Sozialistische Volkswohlfahrt (NSV).
The dimensions are 6 x 8 centimeter, it has 8 pages.
Very hard to find and in excellent condition. Missing from most Luftschutz collections.
