"A result is "Not for Sale," an unusual exhibition that opens Sunday
at P.S. 1, made up entirely of works that well-known artists have
created over the years and then, for a variety of reasons, have
decided they will not sell, no matter the price (they promise, on
their honor)."

I used my own art with my kiddies. I have one piece that I was offered
$300 for - unframed. I wouldn't sell it for a million dollars. My
kiddies said, well couldn't you just make another one? The answer was
no. Some art is not made to be sold. I made my "Celestial Family" as
a gift to my son. Eventually, it will be hanging in his home. I still
have it in my office.
