Art auctions are events where artworks are sold to the highest bidder. These auctions can take place in person at galleries or auction houses, or online through various platforms. Participants can bid on a range of items, including paintings, sculptures, and photographs, often from well-known artists like Pablo Picasso or Vincent van Gogh. Bidders typically register in advance and may need to provide identification. The auctioneer starts the bidding at a set price, and participants raise their paddles or click buttons to place bids. The auction concludes when no one is willing to bid higher, and the artwork is sold to the highest bidder.
