A security guard at a Russian art museum made quite a first impression when he defaced an exhibition painting during his first day on the job. Anna Leporskaya's avant-garde artwork Three Figures, on display at Boris Yeltsin Presidential Centre's "The World as Non-objectivity. The Birth of a New Art" exhibition in Yekaterinburg, was discovered in December to have been defaced with doodles of two sets of eyes. The painting, dated sometime in the early 1930s, features three figures with round, empty faces lacking any features – which changed when two museum guests noticed little round eyes added with a pen to two of the smaller figures. This week, the offender was revealed as a security guard from a private security firm, who is being charged with vandalism. The motives of the 60-year-old guard – who remains anonymous but has since been fired – "are still unknown, but the administration believes it was some kind of a lapse in sanity," said Anna Reshetkina, the exhibition's curator. Restoration on the painting, which is worth in the vicinity of $1 million, will cost an estimated $4,600. The piece has been returned to the State Tretyakov Gallery in Moscow, which had originally loaned it to the Boris Yeltsin Centre.
