BOULDER, Colo. – Authenticity and provenance form the bedrock of Artemis Gallery’s auction business. In their beautifully illustrated catalogs, the company provides bidders with a virtual history lesson in each of its expertly written catalog descriptions. Scrupulously researched, each item is described in depth and tagged with a record of former ownership and previous appearances at auction, whenever such information is available. Provenance of this type is especially important to bidders who participate in Artemis Gallery’s premium-level “Exceptional Antiquities, Asian & Ethnographic” auctions, the next of which is slated for Thursday, October 8. In this series of upscale auctions, Artemis Gallery presents its finest selections from private and institutional collections, with absentee and Internet live bidding through LiveAuctioneers.
