Collection includes Flige's memoirs, which discuss such topics as his childhood and education; ballet and theatre; Kiev and St. Petersburg; his great-uncle, N.Kh. Bunge, his father-in-law V.N. Kokovt︠s︡ov, and Sergeĭ Witte; and of the 1917 Revolution. There are also essays by him on such topics as insurance companies, on the business world of St. Petersburg, and on agrarian issues. Notes and materials collected by Flige evidently relate to a planned book on the fate of the Imperial family during the Revolution. Printed materials include M. Gert︠s︡enshteĭn's, "Agrarnyĭ vopros" (1906), and Aleksandrov's, "Nekotorye dannyi︠a︡ po agrarnomu voprosu" (1917).
