This postcard shows a picture of Lenin’s room at the Aliluyevy Apartment in St. Petersburg.
The apartment originally was rented by Stalin’s parents in law during 1916-1918. In july 1917 Lenin was accused of being a spy and took shelter in this apartment with Zinoviev (who was executed by Stalin in 1937). Lenin stayed only 3 days in this apartment when he fled to Finland to return in October when the Bolsjevik revolution broke out.
In that time Stalin was one of the Bolsjeviks leaders. Stalin himself lived in this apartment a few months in 1918-1919.
This apartment is also called:”Lenin’s secret apartment” and turned into a museum in 1937 and it still is.
