Reproductions of artwork, also known as prints, are usually photomechanical reproductions produced in a commercial process.  They may be in open (not numbered) or limited (signed and numbered) editions.  Giclees (zhee-CLAYs) are a part of this, although I have not used this process in my work so far.  Once the limited editions have sold out, no more of the same image may be reproduced.  Although I do not have as many reproductions of my work as I once did, especially the annual Christmas prints are very popular and very collectible.
