In 1927, the National Geographic Society commissioned American painter N. C. Wyeth to create a series of murals for the walls of our Washington, D.C., headquarters. The face of this handsome thermometer/hygrometer is a reproduction of his Western Hemisphere mural from our private art collection. The large dial displays the temperature while the smaller inset dial displays humidity. Suitable for indoor or outdoor use. 13 1/2" diameter.
