Due to the treatment of Metro stations as possible canvas for art, characterized by the fact that workers of Moscow would get to see them every day, many Stalin-era metro stations were built in different "custom" designs (where each station's design would be, initially, a massive installation on a certain theme. For example, Elektrozavodskaya station was themed solely after nearby lightbulb factory and ceramic ribbed lightbulb sockets); the tradition of "Grand Designs" and, basically, decorating metro stations as single-themed installations, was restored in late 1979.
