Rare Vintage Joygift Thermostat House Man Woman Figures

Up for sale is a rare vintage Joygift? hanging thermostat. This unique thermostat is embedded in a miniature house. You can turn the knob on top of the house to turn the man / woman figurine left and right. Unfortunately it's missing the glass tube and mercury? that made up the thermostat. Also a few decorative pieces in front of the house is missing. Overall this miniature house measures 5.5"x5"x3". Sold as is, no returns. Thanks!
