May 13, 2009 auction held in Canada, the auction house IEGOR. I have a couple of times cooperated with them. Several years ago, they sold several works Z. Serebryakova. On my request, sent a detailed provenance and condition report with detailed photos. Then the estimate for these works was somewhere in the region 22000-25000 of Canadian dollars (now do not remember exactly). I somehow thought and thought and did not participate. In the same year, the same work appeared in MakDuggals a very different price - I think zero was added and the price was already in pounds
And now the auction exhibited one work Serebryakova. This pastel, 48h63 cm, 1932. There is a certificate of Catherine Boncenne. Even at the auction and sell Pozhedaeva Zvereva, see:
