from http://en.wikipedia.org/wiki/Rusakov_Workers%27_Club:
The Rusakov Workers' Club (Russian: Дом культуры имени И.В.Русакова (рабочий клуб)) in Moscow is a notable example of constructivist architecture. Designed by Konstantin Melnikov, it was constructed from 1927 to 1928.
In plan, the club resembles a fan; in elevation, it is divided into a base and three cantilevered concrete seating areas. Each of these can be used as a separate auditorium, while if combined, the building seats over 1,000 people. At the rear of the building are more conventional offices. The only visible materials used in its construction are concrete, brick and glass.
The function of the building is to some extent expressed in the exterior, which Melnikov described as a "tensed muscle".
In 2005 a commemorative coin (3 ruble, silver) was issued by the Central Bank of Russia, featuring Rusakov Workers' Club building [1].
