MOSCOW (AP).- A gigantic sculpture that is one of the most admired examples of Soviet socialist realism is back on view in Moscow after six years of restoration. The stainless-steel sculpture, called “Worker and Collective Farm Woman,” was unveiled Friday in a nighttime ceremony with fireworks attended by thousands. The 24.5-meter (80-foot) sculpture depicts the two figures striding forward purposefully, their raised arms holding a hammer and sickle to replicate the Communist symbol. The worker’s sash and the woman’s skirt float behind them, as if they were moving at high speed. The 72-year-old sculpture by Vera Mukhina
