No Fishing from the Public Water Dept. in Norwalk

A great looking tin sign advertising No Fishing or Trespassing from the Public Water Dept. in Norwalk. I'm assuming that to be Norwalk Connecticut. 

It has wear and dents from use with some rust on the back side. The colors are bright. It has the nice green back you look for in the old original signs. The "Scioto Sign Co. Kenton O." is the sign maker.

It looks to be from the late  1940's or 50's. It is one sided. Measures about 12 inches long and 7¾ inches tall.
