Bomb Shelter signs from WWII
In my hometown the signs from WWII are protected by law and regularly maintained for historical reasons.
These two arrows were indicating the entrance to an underground bomb shelter. Other shelters are marked with "RIFUGIO" surrounded by a black circle.
Nikon 1S2, 1-NIKKOR VR 10-30mm f/3.5-5.6 PD-ZOOM (kit lens). Evening photo. The PD lens retracts when powered off, camera fits any pocket.
