Terms & Conditions

Conditions of sale for auction: This constitutes Concept Art Gallery's and the Consignor's entire agreement with the purchaser relative to the property to be sold at auction. The following Conditions of Sale are the complete and only terms and conditions on which all property is offered for sale. All property is sold "AS IS" and neither we nor the Consignor makes any guarantees, warranties or representations, expressed or implied, with respect to the property or the correctness of the catalog or other description of the authenticity of authorship, provenance, exhibitions, literature or historical relevance of the property or otherwise. No statement anywhere, whether oral or written, shall be deemed such a guarantee, warranty or representation. Any condition statement is given as a courtesy to a client, is only an opinion and should not be treated as a statement of fact. Concept Gallery shall have no responsibility for any error or omission. The absence of a condition statement does not imply that the lot is in perfect condition or completely free from wear and tear, imperfections or the effects of aging. Prospective bidders should inspect the property before bidding to determine its condition, size and whether or not it has been restored. We and the Consignor make no representation or warranty as to whether the purchaser acquires any reproduction rights in the property. We reserve the right to withdraw any property before sale. Unless otherwise announced by the auctioneer, all bids are per lot as numbered. We reserve the right to reject any bid. The highest bidder acknowledged by the online bidding system will be the purchaser. In the event of any dispute between bidders, or in the event of doubt on our part as to the validity of any bid, the auctioneer will have the final discretion either to determine the successful bidder or to re-offer and resell the article in dispute. If any dispute arises after the sale, our sales record is conclusive. Although in our discretion we will execute order bids or accept telephone bids as a convenience to clients who are not present at auctions, we are not responsible for any errors or omission in connection therewith (applies to Live Sales only, no phone/absentee bids for Online-Only Sales). If the auctioneer decided that any opening bid is below the value of the article offered s/he may reject the same and withdraw the article from sale, and if, having acknowledged an opening bid, s/he decides that any advance thereafter is insufficient, s/he may reject the advance. All sizes are approximate. All transactions must be complete before property is removed from the premise. Possession of purchased property will not turn over to bidder until checks have been cleared or arrangements for payment have been made with the Gallery. Cash (in house only), certified check, Master Card, Visa, Discover, (bank) wire transfer, or personal checks with prior approval are acceptable terms for purchases. If an article sold cannot be delivered by reason of theft, breakage, or other damage prior to check- out, the sale shall be deemed canceled without any liability on the part of the Gallery. All merchandise must be paid for and picked up or shipping arranged immediately following the sale, in no case later than one week following the sale, by 5PM (see shipping details to make shipping arrangements). Items not picked up by the deadline will be charged a storage fee of $5/day per lot. Additional charges may apply to oversize lots. Shipping can be arranged through any third-party shipper (find list of suggested shippers at our website). Merchandise not picked up will be re-auctioned or resold without further notice to the purchaser and payments will be forfeited. Further, in the event of loss or such resale, the original will be responsible. Property not picked up within one (1) month may be re-auctioned or resold without further notice to the buyer, and payment will be forfeited. Merchandise will be packed and transported by the purchaser at their own risk and expense. Bidding on merchandise automatically constitutes agreement with these terms. IMPORTANT NOTICE: A premium of 24% will apply to all property sold at bid.conceptgallery.com, to be paid by buyer as part of the purchase price. Phone & absentee bids are available until 5pm the day before the sale (applies to Live Sales only, no phone/absentee bids for Online-Only sales). Lots including jewelry, silver or other precious metals can only be paid for by wire transfer, bank transfer, ACH transfer, cashier's check or an in person cash transaction. All lots with these payment restrictions will be noted in the Condition field. Auctioneer License: Sam Berkovitz AU003292-L; Alison Oehler AU005978
