Dorothy Ami is known for her traditional style of Hopi pottery.  This bowl is painted with a series of bats which extend around the top of the bowl.  Note that there are different designs on the wings of each bat.  As well, the colors of the bat wings are derived from natural clay slips.  The black is from bee-weed (a plant).  The bowl has been traditionally fired to create the various blushes on the surface.  It is in excellent condition with no chips, cracks, restoration or repair.  It is signed on the bottom in the clay.
