Nolan Youvella was a son of noted potters Iris Nampeyo and Wallace Youvella.  He was known for his relief carved and incised pottery.  This jar is one of his famous Pueblo building and kiva bowls.  The piece has four buildings in relief and two kivas.  The adobe bricks of the buildings are all incised into the clay.  While I have seen larger versions of this style of his work, this is one of the most intricate and tightly designed.  The top and bottom are polished tan, the natural color of the clay.  The jar was traditionally fired so there are subtle blushes on the surface.  The piece is signed on the bottom in the clay, “Nolan Y.  Nampeyo”.  It is in excellent condition with no chips, cracks, restoration or repair.
