The primary function of an art market is to provide a platform for the exchange of artworks between buyers and sellers.

Museums are not typically considered to be art markets, as their primary purpose is to preserve and exhibit works of art, rather than to facilitate their sale.

Museums play a vital role in promoting and educating the public about art by providing access to artworks, organizing exhibitions, and offering educational programs.

The value of art is influenced by a combination of factors, including the artist's reputation, the age and condition of the artwork, its rarity, and its historical significance.
