  CULTURAL REALISM   A mural of happy communists graces the side of the current home of the Federal Ministry of Finance in the former East Berlin. The building was built in 1935 as the Reich Ministry of Aviation. During the Cold War it became home to the House of Ministries.&amp;nbsp;The House of Ministries was also part of the demonstrations that took place in June 1953, when the protesters gathered there to demand social reforms and free elections. Hundreds of demonstrators were killed and thousands more were jailed. Several Soviet soldiers were reported to have been executed for their refusal to shoot unarmed demonstrators. Today a monument in front of the ministry commemorates the June uprising.
