Printmakers just can't leave enough alone. It may take years to sell an edition, so two or three years later you may look at your image and say I don't like the way I did that or I think I'll make a little change of mood there.
If it is a very little change I'd keep the edition and state the same. If it a big change then I would call the print a new state or indicate that I've cancelled the first edition at a given number and rename the image.
Well, I've done just that with Jester Gesture-Fond Memories, now she is Jester Gesture-Heartbreaker. I've cancelled Fond Memories at an edition of 3 and altered it to Heartbreaker.
Now, have a little fun and spot the major alterations that changed the image.
