MOSCOW (AP) — Vladimir Lysenko's painted bull stares with flat black eyes like a double-barrel shotgun, one of his horns festooned in a mosaic of bright rectangles, the tip of his tail stretched toward a glowing orange globe that may be the sun. Over the years, the painting has become one of the most renowned images of the artistic ferment that bubbled under the strictures of insipid Soviet social realism. Bold colors, dancing polygons and strange faces disappeared from the public view, replaced by muscular construction workers and children devotedly presenting bouquets to Soviet leader Josef Stalin. Savitsky began collecting as much of the "unofficial" Soviet art as he could, reportedly filling train sleeping compartments with paintings to bring them to Nukus, some 2,000 kilometers (1,200 miles) from Moscow. Many of the works likely would have been destroyed or deteriorated irreparably if he had not been able to spirit them away to a city far from the central government's attention.
