The term has one meaning, an edition that is restricted to a specific number of copies.  Most modern artists produce only limited editions, (the number printed), normally signed by the artist in pencil, and numbered to show the unique number of that impression and the total edition size

There is no limit to the number of prints in the edition. Prints may be signed by the artist.  Each Print is a Full Color reproduction from original oil paintings. Our open editions are published with all acid-free materials to archival standards.
