This is a very unusual plate by Juanita Pena is from the 1930’s. It is polished and polychrome with a bird as the design.  The bird is a combination of black mineral slip and a red slip.  The back of the plate is signed, “Juanita P.”. While it should be an easy piece to attribute to Juanita Pena, Russell Sanchez told me that Juanita Pena never made polychrome pottery and he thinks the “P” after the name is not a letter.  So, if not then the plate would be by Juanita Gonzales.  I does strike me a bit more like Juanita Pena’s style of design.  Either way, there are very few polychrome pieces in general by this time. The piece was deacquisitioned by a museum and its original acquisition date was 1938.  Either Gonzales or Pena, it is a charming piece!
