Dating to the turn of the century this is a great early porcelain ceramic door sign. As ceramic is fragile, it is a very rare sign as they mostly cracked or broke, not many have survived.
In forty plus years of collecting, I've never seen another. Please scroll through my other items as I will be listing a similar ceramic door sign. The condition of them both are excellent, no chips or cracks with lots of character and a nice shine to the porcelain.
