ST. PETERSBURG (AP).- President Dmitry Medvedev has outdone his powerful predecessor — as an artist. A photograph Medvedev took of the kremlin, or fortress, in a Siberian town sold for 51 million rubles ($1.7 million) at a charity auction Saturday night, surpassing the 37 million rubles (then $1.1 million) paid last year for a painting by Prime Minister Vladimir Putin. Medvedev’s black-and-white photo was snapped up by Mikhail Zingarevich, a board member at Ilim Group, the pulp and paper company where Medvedev once worked as a lawyer. Zingarevich said he planned to hang the 69-by-96-centimeter (27-by-38-inch) picture in his office.
