If you don't own original work anymore, can you still sell prints?

[ChantalFournier]

You should send a personalized letter with each sale that names the painting, thanks them for their purchase and reminds them that you retain the right for licensing and reproduction. A kind of thank you note/invoice. You keep a copy of each for your records and note when you first put it online. If you have working files of the preliminary sketches, you keep them.
