According to RIA (Russian TV):
Russia’s provincial town of Penza has got onto a Forbes magazine list of the most unusual museums all over the globe.
Penza’s museum exhibits only one painting – by none other than our favourite Dutch classicist Rembrandt. The picture is accompanied by a whole range of historic materials and videos.
The museum, founded in 1983 by historian Georg Myasnikov, a secretary of Penza committee, was named by Forbes as one of the most interesting single-exhibit museums and remains the only permanent one-painting museum in the world.
Among other museums that entered the Forbes list are the Vase Museum in Stockholm, the Shroud of Turin Museum in Turin, the Freedom Bell museum in Philadelphia, Pennsylvania, and the Moon Museum.
