All results include the fees and premiums added to the price of a work of art when the auctioneer's hammer falls. Sale prices are compared to the auction house’s low estimate, which do not include premiums.
Guarantees: Sometimes an auction house guarantees to pay a seller for a work, regardless of whether the bidding reaches the reserve price, a figure that is typically confidential.
Bought-in: If there are no bids for a work, or if bidding falls short of the reserve price, the lot is unsold or “bought-in”.
Withdrawn: This happens when a seller decides, for whatever reason, to withdraw a work before the bidding begins.
Premiums: Typically a sliding-scale of charges paid in addition to the hammer price by the buyer, plus any other fees.
