Avoid commercial limited editions i.e. signed and numbered reproductions. These are not the same as original prints. If you don’t know the difference between photo-mechanical copies and traditional fine prints, you should read up on the subject, ask a museum curator about this, or better yet, get the facts from a printmaker directly.
Limited Edition is a marketing strategy designed to create the impression of scarcity (hence value) in common copies of paintings. New digital printing processes, like giclee (ghee-clay), are very slick and priced right up there with original prints. They are the worst value in prints because a) they cost more than other reproductions b) they are not original prints, like you find in museums and good private collections c) people who know prints consider artificial limited editions an unfortunate deception on the unsuspecting public.
