Valery clover (clover) - Klever

[Alenka]

Distinguished professionals, experts and amateurs! Thank you for your help on "Previous issues. But a new question!
Tell me please, someone has ever faced it with the works of Valery clover. If yes, then could not tell the approximate cost of oil on canvas, 60-70 years. (ie, before immigrating to 1978) and the approximate price of the schedule. Some of his works is at SITE. Works great, somewhere 95h150 see more. It is possible to acquire the collection, but here's my snag with the definition of "best" price . Works quite interesting.

Advance grateful.
