Lost artworks are works of art that have been lost or destroyed and are no longer in existence. These artworks can range from sculptures to paintings, and can be created by anyone from a famous artist to a 5 year old child. Artworks can be lost in many ways, such as when a painting is damaged or destroyed in a fire, when a sculpture is stolen, or when an artwork is lost because it has been forgotten over time. It's really sad when an artwork is lost, because it can never be seen, admired or enjoyed again.
