Although this exquisite jar has been attributed to Nampeyo, it was almost certainly painted by someone else. The elongated triangle motifs are often referred to as batwings, although the origin of this interpretation is unclear. The entire style with the hatched background is consistently referred to as a migration design, with the lines suggesting the paths taken by clans as they descended upon Hopi.
Nampeyo scholar Barbara Kramer has found that Nampeyo was less likely to render this design in the great detail that her two daughters later did, and notes that where a bar of diagonal lines appears in the wing design on this jar, Annie would more likely have had dots. For this reason and due to the higher than average shoulder on the jar, Kramer puts her money on granddaughter Rachel as the painter.
