LONDON— Konstantin Somov’s painting The Rainbow (1927) sold for $7.3 million at a Christie’s sale in London on June 13, shattering a record for a work at an auction of Russian art, Bloomberg reports. Eighty-five percent of the buyers were from Russia, according to Christie’s. “When Russian collectors want something of top quality, money is meaningless for them: They will pay crazy prices,” said James Butterwick, a Russian art dealer in London. “In my 20 years of dealing with Russian art, I've never seen such a fine Somov.”
