Do you think an old painting based on lord of the rings, would be worth any money?

Its these old painting my uncle have we are trying to find out if they are worth any money. They are different old paintings of different parts of the lord of the rings. like one of them has bilbo going to Rivendell on a boat. I dont know how old they are but i know they had them way before the movies came out and before i was born which 1991 and i think they had it before or around the 80's too.
