This bowl is unsigned from around 1936.  It is stone polished and has a lightning design around the neck (or a very stylized avanyu) and triangular design around the shoulder.  The triangles have hatchwork painting and there are small dots around the lightning. While it is unsigned, the sticker on the bottom is from the 1936 Santa Fe Indian Market.  It’s always fascinating to find pieces with these stickers.  The bowl is in very good condition with cracks, restoration or repair.  There is one little chip on the inside of the rim.  Definitely a piece of history!
