This wide shoulder bowl by Juanita Pena is from the 1930’s and it is carved with an avanyu as the design.  Juanita and Tony Pena had a particular style to their avanyu with the triangular eye.  As well, the carving was more in the “cameo” style, as note that the avanyu is in raised relief. It is the small details which are so striking on their work, such as the polished rim and the polish at the base of the bowl.  It is signed, “Juanita, San Ildefonso” and it is in very good condition with no chips, cracks, restoration or repair.
