Question on sales prices of paintings

[Прохожий]

And not only collectors, but that is typical, and dealers, too. The collector is responsible only to itself, on the basis of his eye - smotrok, or so favorite auctioneers "caveat emptor". The dealer is responsible to the client, especially its reputation, and, of course, money. Maybe for someone really is not a question of principle, a picture of in 1950 or in 2008 (agree, that is, to put it mildly, strange), just to work like it ... But, in my opinion, this situation is possible only in the event that the case of very inexpensive things, but when you pay for work of art, which is viewed as more than aesthetically pleasing object, of course desirable to have as much information.
