Vintage Enamel Sign: Fire water burns

Foreign vintage safety signs often give you a less serious interpretation of what they used to warn for. C'mon party people; we don't need no water let the MF burn — burn MF, Burn.
Originates from Bulgarian charcoal mine. Nicely hand made with slight relief. In fairly good condition, but contains small scars from the tooth of time. Round sign in orange and black. Images are pretty dark — objects are brighter than you might believe.
Diameter: 32 cm. Two original drilled holes make it easy to fix 'm on the wall.
