This is a classic long neck shaped jar by Dorothy Torivio.  She was among the first to utilize and then refine the “op-art” style in her Acoma pottery. She took classic Acoma patterns and then repeated them on a vessel, ranging the size from small to large and then small again, in accordance with the shape of the vessel.  The shape of the jar is one that Dorothy created to emphasize her painted designs.  The wide shoulder extends upward to the elongated neck.  The entire piece is painted with an interlocking butterfly design.  It starts small at the rim of the neck and gets larger at the shoulder and smaller at the base.  The black and white coloration gives the jar a very modernist appearance.  The precision and tight painting on the neck is exceptional!  The jar is signed on the bottom, “Dorothy Torivio” and it is in excellent condition with no chips, cracks, restoration or repair.
