One of a series of 'Air Raid Precautions' cards. One of several types of air raid shelter, this model is entirely below ground, roofed and walled with corregated iron and covered-over with sandbags. Despite widely being regarded as a useful source of instruction, production of cigarette cards was halted during both World Wars due to shortages.
