This is a highly polished melon bowl by Nathan Youngblood.  It was made in 1977.  There are nine ribs swirling from the rim to the base.  They are wider at the top and narrower at the base of the bowl.  The entire piece is fully polished and fired a glassy black. The jar is signed on the bottom in the clay “Nathan Youngblood” and the hallmark of his name in Tewa.  It is in excellent condition with no chips, cracks, restoration, or repair.
