From the point of view of the purist, the irony as far as pricing art is concerned is that:
(a) a piece from his collection is eventually sold at the same price that he had estimated it to be its real worth years earlier
(b) his art is subjected to the same market forces against which he strove his entire life
(c) "realities of the market place" is a concept that negates the very atributes that we associate with art- whim, fancy and imagination
