What You Are Buying
What you own.
- Any painting you buy from me is yours to own
- Pass on
- Do anything else you want.
What is not yours is the copyright to that painting.
The copyright has an independent value; such as to a publisher, who wants to use the image for commercial purposes. I retain the copyright, though you may negotiate to buy that too.
This is very much a legal and standard way of handling art sales, although very few dealers admit it.
