Art Pottery Square Shape Cup or Mug.  It has on the outside CUBA which is raised paint lettering.  It also has the Tonala Pottery look with the Black Raised Paint Technique.  The colors on this piece are a Burnt Orange, Purplish Blue, and White.  The inside has been glazed as well as the outside.  The piece is not marked but definately Hand Painted and Crafted.

This cup or mug if not used as a drinking item would make a nice small planter for maybe an air plant or any plant that can hang over the opening.
