Every year, it holds the biggest fine art auction house. This event is named the Hambons Annual Fine Art and Antiques Auction, and is the focus of attention of businessmen, dealers and several art collectors. It is also the island's main income source. Because of this, it is the Auction House's priority to exist and to be held every single year, in order to maintain the island's economy. It was founded by Hambons, one of the richest men in the world and the mayor of Guernica Island.
