Art is very valuable because most art is from a long time ago. The painter must be very important. The painter has probably died or is very old. If the painting was fake there would be a few hints. Each painter has a different way or painting or a different streak. Art is very important, not just because of the painter, but how long its been around. If the art is a replica, then it isn't valuable. Replicas aren't valuable because they aren't the same. HOPE THIS HELPS:)
