Rare Arts & Crafts copper finished metal humidifier by Walton.  Circa 1920.  In beautiful condition for its age, and complete with all its bits, this is the only example of the Walton humidifier that I have seen in Arts & Crafts style.  The copper finish has some age, but the Walton logo transfer on the front is largely complete.  Wonderful design,  wonderful scroll handles, and wonderful condition.
