Hopi Tuhisma - 5th Annual Hopi Tuhisma Arts and Crafts Market. "LOMA" artwork is a hallmark or trademark. Since the Hopi word pertains to corn, I use the "loma" and then 4 corn stalks as my signature says Mr. James. 23"w x 30"h. Artist: Dalton Buddy James, a member of the Tobacco clan from the village of Hotevilla.
