Old Safety Supervisor Green Cross Enameled Brass Pin

I found this one at the flea market and just thought it would make a good stocking safety for someone who is especially good at watching and guarding on behalf of the safety of everyone around them! It's a nice old heavyweight pin, enameled brass I believe, and I think the only thing better than a Red Cross may be a green one!

2" diameter. I might guess 1940s or so. Very good condition.
