Plates and Bowls is self-defining, although the pueblos do make some plates and bowls that are really small and others really large. The larger bowls also seem to be more utilitarian than decorative while plates all seem to be purely decorative.
There are still quite a few older, unsigned large dough bowls from Zia and Santo Domingo floating around. Most I have seen were clearly utilitarian. I've even found a couple with bits of dough still in them. I've seen smaller bowls from most pueblos and miniature ones from Kimo Decora of Isleta and Thomas Natseway of Laguna.
Some potters in Mata Ortiz also have plate and bowl construction down really well, but their work is also purely artwork as the entire Mata Ortiz/Casas Grandes revival has never been about utilitarian pottery.
Above my desk is a Hopi-Tewa yellow ware bowl made by Nyla Sahmie. The inside is painted with the mythical "bird hanging from sky band" design, an image that goes back more than 700 years. Nyla is a great-great granddaughter of Nampeyo, a woman attributed with the rebirth of prehistoric Sikyatki designs and yellow ware pottery.
I've worked with Nyla and her sister Rachel to determine the authenticity of pottery attributed to Nampeyo. Nampeyo never signed anything but after she went completely blind (around 1920), her daughters did her painting for her. Fannie (Nampeyo's youngest daughter) would sign "Nampeyo Fannie" on pieces her mother made and she painted. (On her own pottery, Fannie signed "Fannie Nampeyo". Annie Healing (Nampeyo's oldest daughter) painted a few for Nampeyo but I have yet to see one that was signed.
When Rachel checked out the physical and design characteristics of each piece she explained to me what she was looking for as she did it. Nyla just held the piece in her hands and "felt" the clay. I handed Rachel a piece that I knew was a bit different and her almost immediate response was "Nope, this isn't from Grandma." Then she handed it to Nyla who held it in her hands for a moment and said, "This was made by Grace [Chapella]. Grace lived across the street from Grandma. Grandma taught Grace how to make pottery."
The piece in question was between 80 and 100 years old, decorated with Awatovi and Sikyatki-style designs and in excellent condition. It also had several images of the moth on it, more a signature design of Grace than of Nampeyo. The piece was made after most of the Hopi-Tewa made the changeover to Jeddito yellow clay, a changeover elicited by Nampeyo's growing success in the marketplace. That would have put its creation between 1915 and 1935. But it wasn't signed and Grace was one of the first to sign her pieces, beginning somewhere around 1925.
