AUTHENTICATION & PROVENANCE OF ATTRIBUTED LOTS (and lots offered "in the manner of"): This lot is being offered as "attributed to" the named artist. We have no specific documentation to prove or disprove its authenticity, nor have we submitted it to any expert or committee of experts for review or forensic examination. Authentication is not an exact science. Contrary opinions may exist. Our opinion is not based on any specific expertise. The signature, style, and composition of the work seem absolutely correct and are similar to pieces of known authenticity and provenance which we have seen or sold, although neither we nor the consignor can guaranty that the present lot is wholly or partly by the ascribed artist. Regarding provenance, at times we rely on information provided to us by the consignor, the consignor's agent, family records or documents, estate papers, and/or other third parties. Sometimes this information cannot be verified. If you have questions about a lot's provenance, please ask them prior to bidding. Unless stated otherwise, no documents, letters, or additional information concerning provenance will accompany the lot. [Copyright 2014 Preston Hall Gallery]
