BOULDER, COLO.- An eclectic mix of American history, devotional art, Indigenous craftsmanship, luxury watches, jewelry and natural history will come together on August 24, when Artemis Fine Arts opens its American Frontier | Ethnographic | Tribal Art auction in Boulder, Colorado.

Curated by Bob Dodge, the sale reaches well beyond the American frontier suggested by its title, bringing together objects from Latin America, New Zealand, Southeast Asia, Europe and prehistoric North Africa. The auction begins at 9 a.m. Mountain Time and includes material described by the auction house as legally acquired and guaranteed as catalogued.


Peruvian Demanda, Painted Wood Shrine, Virgin of Sorrows, 1857. Estimate: $8,000 - $12,000.

Among the most visually arresting lots is a Peruvian portable devotional shrine, or demanda, dated 1857, estimated at $8,000 to $12,000. Closed, the painted wooden cabinet presents the image of a crimson heart pierced by a sword. Open its hinged doors, however, and an intimate devotional world appears: a standing Virgin of Sorrows dressed in silk and lace, framed by painted architectural elements, flowers and religious imagery.

The shrine was not simply intended to remain in a church. Such objects traveled from household to household during devotional observances, gathering both prayers and alms. A small drawer at its base was used to collect coins.

What makes this example especially compelling is its unusually precise history. Painted inscriptions record that Guillermo Lazaro and his wife Dorotea Sacsabilca presented the shrine to the town of Santiago de Cochahuayco, in Peru's Lima region, on April 2, 1857. For an object designed to travel, survive handling and pass from one generation to another, that firmly documented date and place give it an uncommon sense of immediacy.


Sam Houston Ivory Portrait Locket, Family Provenance to 1863. Estimate: $9,000 - $13,000.

Another object with an unusually personal connection to history is an ivory portrait miniature of Sam Houston, one of the central figures in the history of Texas. Estimated at $9,000 to $13,000, the portrait depicts Houston around 1840, the year he married Margaret Moffette Lea.

Set inside a gilt brass locket, the miniature was meant to be carried close to the body rather than displayed formally. A compartment on the reverse could hold a lock of hair, turning the portrait into something more intimate than a political souvenir.

According to the auction catalogue, the portrait formed one half of a pair made for Houston and his new wife. Margaret reportedly wore this portrait, while Houston carried hers beneath his vest. The locket remained in the Houston family for generations, with provenance tracing it from Houston through his sons and later descendants before entering a New Mexico collection.


Rolex Lady-Datejust 69173 NOS, Full Set, Box & Papers. Estimate: $10,000 - $15,000.

The auction also moves dramatically forward in time with a Rolex Lady-Datejust reference 69173, dating to around 1997–1998. Estimated at $10,000 to $15,000, the two-tone steel and gold watch is being offered as new old stock, complete with its original box, warranty certificate, hang tags, booklets and other accessories.

Its champagne dial, fluted gold bezel and Jubilee bracelet make it instantly recognizable, but for collectors the completeness of the package may be just as important. The watch still retains protective stickers on the caseback and clasp and is described as unused.


20th C. Sulawesi High-Karat Gold Bangle - Filigree Floral Rosettes. Estimate: $11,000 - $16,000.

Jewelry collectors may instead gravitate toward a high-karat gold bangle from Sulawesi, Indonesia, estimated at $11,000 to $16,000. Tested at approximately 21 to 22 karats and weighing 42.5 grams, the bracelet combines intricate filigree wirework, floral rosettes, scrolls and granulation.

Its delicate surface reflects a goldsmithing tradition in which precious metal was drawn into fine wire, twisted and coiled into elaborate patterns and soldered onto a thin backing. The technique allowed craftsmen to create jewelry with an imposing visual presence while using the metal with extraordinary finesse.


Maori Muka Korowai Woven Cloak - Hukahuka Tags & Red Wool Pompoms. Estimate: $7,000 - $10,000.

One of the sale's most culturally significant textiles is a Maori muka korowai cloak from New Zealand, estimated at $7,000 to $10,000. Woven from prepared New Zealand flax fiber, the cloak is decorated with black hukahuka tags and vivid red wool pompoms.

Korowai are far more than decorative garments. Traditionally produced through painstaking hand-twining techniques, they could embody status, ancestry and the spiritual presence of their makers and wearers. The catalogue notes that such cloaks represented months of skilled labor and could transmit mana through inheritance or gifting. This example, dating from approximately 1880 to 1940, is professionally mounted for display.

And then there is an object that pushes the auction's timeline back not centuries, but tens of millions of years.


Fossilized Crocodyliform Skull w/ Teeth - Moroccan Phosphate Beds. Estimate: $5,000 - $7,500.

A fossilized marine crocodyliform skull from Morocco's Oulad Abdoun phosphate basin, estimated at $5,000 to $7,500, dates to approximately 34 to 66 million years ago. The elongated skull retains rows of conical teeth, with additional skeletal fragments preserved in the surrounding sediment.

The fossils come from geological deposits spanning the end of the Cretaceous and the early Paleogene—a period that includes the mass extinction that ended the age of the non-avian dinosaurs. Marine crocodyliforms, including long-snouted dyrosaurids, were among the animals that survived across that boundary.

Taken together, the featured lots give the Artemis Fine Arts sale an unusual rhythm. A nineteenth-century Peruvian family commissioning a shrine, a newly married Sam Houston carrying his wife's likeness close to his heart, an Indonesian goldsmith patiently twisting fine strands of nearly pure gold, Maori weavers building status and memory into fiber, and a prehistoric predator preserved beneath an ancient sea all occupy the same auction catalogue.

That range may be precisely the appeal. Rather than telling a single story, the sale offers a collection of objects that have survived for radically different reasons—devotion, love, prestige, craftsmanship, collecting and, in the case of the Moroccan fossil, the extraordinary accident of geological preservation.
