So what else is ridiculous, some gallery owners and even customers, too, when answering the question how much does raise eyebrows in surprise (worked-out position :)) and say so clearly: yes, you just now that we have at the club "Wasi" three times cheaper than purchased. Buy-buy now sells. :D :D

Being a fan Khrushchev - manifestations of plastics and unobtrusively, I do not believe that he could create it. And this comes easily to me: almost regular geometrical shape of the body, painted "the same" paint, geometric "Zelenka" in the background, the overall dark-pritemny coloring may remind Moscow of the sixties, but not the Odessa nonconformists.
  If something is one of the above items, as well as all-in one work. Maybe he just decided repeat some "avant" for fun? But Khrushchev has one feature - his signature is no less artistic burden of the work itself, especially when such a bright color. Then this art is not noticeable, but noticeable, some technical oddities signatures.
  Вобщем, bust strange in one work. Very often the work plan for me below the first, and then suddenly this "discovery". Specifically found, and his "dark-geometrical" work for comparison. For me, this and the above - the work of different people.

I advise you to check these works. Why are you so confident that they are 100%authentic?
