DALLAS, TEXAS—The Liz Claiborne and Arthur Ortenberg Collection of tribal art and rarities from the American/Canadian Northwest headline Heritage Auction’s summer Ethnographic Art: American Indian, Pre-Columbian and Tribal auction July 8. Single-owner collections across multiple collecting categories offer fresh-to-market discoveries for collectors, said Delia Sullivan, director of ethnographic art at Heritage, “It was a career highlight to work on the Liz Claiborne and Arthur Ortenberg collection because it spanned so many cultures and artistic styles. . . . This collection has it all.”

The auction begins with American Indian art offering examples of jewelry, paintings, period, original polychrome baskets and clothing. From the Pacific Northwest comes a rare and unusual Northwest Coast feast bowl, probably from the Nootka Indians, circa 1800 ($50/70,000) and an Eskimo carved walrus ivory tusk from Nunivak Island, depicting native fauna including seals, a bear and an eagle ($7/10,000).

The auction continues with a selection of Pre-Columbian gold, ceramics and stone carvings, including an extraordinary life-size Teotihuacan stone mask in dense stone circa 450–650 CE ($20/30,000) and a tall Vera Cruz life and death palmate, a sculpture depicting life on the recto and death on verso, circa 600–900 CE ($15/20,000) introduces the Robert V. Berg Collection. With an academic focus, Berg began collecting African art in the 1960s. While spending time in Paris on a post-doctoral Fulbright, he discovered an emerging community of collectors and dealers who gravitated toward traditional African sculpture as pure forms, rather than simply anthropological artifacts. Selections of his African art collection include the Senufo standing female post figure ($10/15,000).

From the Claiborne and Ortenberg collection of tribal art comes a Dogon standing female figure ($6/8,000) and a monumental Waja shoulder mask standing nearly 4-feet tall ($30/40,000).

Heritage Auction’s Design District Annex, 1518 Slocum Street, will be the site of the auction. For more information, www.ha.com or 877-437-4824.
