There are so many artists that are sought after in the art world with recognisable names including Picasso, Monet, Constable, Dali, Hockney, Warhol, Emin and Hirst to name a few. Art from some of the most sought after names can be worth huge sums of money but lesser known names can also be valuable.
Originals and painted canvasses are usually the most valuable strictly speaking, but even prints can be valuable based on their rarity and market demand. Many people have artwork they’ve held onto for decades or inherited and are unaware of its value.
