An art dealer is a person or business that buys and sells works of art. Art dealers typically specialize in a particular type of art, such as paintings, sculptures, or prints, and they may work with both established and emerging artists. Art dealers often play a key role in the art market by connecting buyers and sellers and helping to facilitate the sale of artworks. They may also provide a range of other services, such as appraising artwork, conservation and restoration services, and offering guidance and advice to collectors and other clients.
