Malachite Mayan or Aztec Calendar

A vintage green malachite Aztec tabletop calendar inspired by the Sun Stone. It has Mexico at its base and the inner circle has figures from ancient Mexican mythology; above Mexico are the heads of 2 monsters or animals. This was originally a clock but the clock portion was both cheap & poorly made so I removed it. The calendar is 7 1/4" wide, 8 3/4 tall and about 2" deep.
