Photograph of the interior of an exhibition pavilion during the 1872 Moscow Polytechnic Exhibition. In the centre of the room there is a large model of a building, split in the middle to show the interior. There are plants around the surrounding pillars and display cases around the edges of the room. A symbol of a cross within a circle decorates the windows, curtains and balcony. The 1872 Moscow Polytechnic Exhibition was one of the largest trade shows held in Russia in the 19th century. It was timed to coincide with the 200th anniversary of the birth of Peter I and showcased advances in areas such as technology, warfare, science and culture.
