Artist Terri Meyer creates the Zodiac clock line to assist you in finding your unique personality qualities. Each of us are born at a given moment, in a given place and possess the qualities of the year and season in which we have entered into. The clock is constructed of medium density fiberboard with a UV protective coating to ensure durability. It includes a hanger for easy wall placement. The clock works are quartz movement and takes a AA battery (not included). Choose from 4 sizes: 10, 16, 24, and 24 inches. Each clock includes a Zodiac card which describes the characteristics of that sign.
