The thaw in U.S.-Soviet relations has warmed up the world of art with the just-announced October mingling of the priceless Faberge egg collections owned by capitalist Malcolm S. Forbes and the Soviet Union.

"The exchange is very closely related to the improvement of relations," Irina Rodimtseva, director of the Moscow Armory Museum, said Friday through an interpreter. "Only when countries and people trust each other can such an exchange take place.""We're calling this egg-nost," said Christopher Forbes, whose billionaire father owns a dozen of the Imperial Eggs. The hand-crafted artworks were designed between 1884 and 1917 and presented to the Russian czars Alexander III and Nicholas II.

The Soviets own 10 of the hand-crafted eggs; San Diego Mayor Maureen O'Connor, whose city will be host of the "Treasures of the Soviet Union" exhibition from Oct. 21-Nov. 11, said the exact number of eggs on display is under negotiation.

As part of the deal, several of Forbes' eggs will subsequently go to the Soviet Union for display in the Kremlin. Christopher Forbes agreed that the Soviets' new openness was the key to the unprecedented loans.
