Wow, Johan, I wouldn't know where to start guessing. I know what his pieces sold for before he became ill, but that would surely change now that he's retired. Made me think about the pieces of his I have- I could NEVER sell them, and if they were destroyed, no amount of money would make me feel better.If she wants to sell the piece, it would be easier to determine a price because "value" is simply what someone is willing to pay. Good luck with this one, and let us know how it turns out.
