I never realized Tootsietoy made such a thing. Did some google image searching and found that the made them for doll houses in the 1920's or 30's. They were also apparently packaged with a ceramic pot to show how far we'd come since 1833 for the 1933 'Century of Progress" World's Fair. Cool find!
I love that tiny toilet! As I get older, I appreciate having one close. I'd put that one on a chain and carry it with me, so I'd never be far from one.
