How do you tell if a lithograph is original?

To tell if a lithograph is original, first look at it closely with a magnifying glass. Originals will typically display noticeable dots, while copies may lack these details. The artist's signature can also be a clue. Most original lithographs will be hand-signed with ink or pen on the back or in a margin. The signature will be printed on a reproduction. Because it can be difficult in some cases to tell reproductions apart from originals, experts often recommend having prints authenticated by a certified appraiser or knowledgeable art dealers.
