I feel that my relationship with Kasparov now is much the same as it had been before the match - good. As for his reaction well it can't be nice to lose your title after so long but he was very generous.
It is a myth that art has to be sold. It is not like stocking a grocery store where people fill a pushcart. Art is a product that has no apparent need. The salesperson builds the need in the mind of the buyer.
