Most of the materials are from the years after World War II, and concern the organizations with which Lampe was affiliated. There is correspondence from members of the Romanov family, especially Grand Prince Vladimir Kirillovich, and from Alekseĭ Arkhangelśkiĭ, Ivan Ilín, Vasiliĭ Orekhov, and others of Lampe's emigre military and monarchist colleagues. Photographs deal with such topics as the Romanov family, the Civil War, the emigration, World War II, and with Lampe himself. Besides the post-1945 materials in the collection, smaller groups of materials concern 18th and 19th century Russian military history (including a letter signed by General Aleksandr Suvorov), the interwar period, and ROVS in Germany during World War Il.
