An art collector is someone who collects art. Art collectors usually collect art for their own personal enjoyment, but sometimes they collect art to sell it later. Some people collect art because they think it will be valuable in the future, while others just enjoy looking at it and collecting it.
Art collectors typically have a deep knowledge about the artists and movements that they collect. They often times spend a lot of money on their collections, and may even travel to different countries to find the pieces they want. Many art collectors also get involved in the art world by attending gallery openings and art fairs.
