Vintage/very old thermometer for outside or inside use.

Vintage thermometer for indoor/outdoor use. This was my grandmothers. She traveled around the world for her job in the 1930s and got this in Geneva! There is some rust on it from hanging it outside. To me, that makes it look even more vintage!! Hand painted. I love it, but I am cleaning out. Can’t keep all of her heirlooms lol
