This fertility goddess mug is from the Mauna Loa in Mexico City, and has the "Mauna Loa" logo printed on its back with the more modern graphics from the second location on San Jeronimo. The mug has a black glaze, and is of a woman down to mid-calf. The arms are separated from the body and clasped in front. Another version of this mug has more swirl details, and is not marked Mauna Loa, but is likely from the same location.
