Besides family photos and letters, there are some unique personal things such as a crusifix and a baby sock (where else would you see Eisenstein's baby sock?!). What do we see in Eisenstein's library? Books on art, literature, history, psychology, biology, philosophy and, of course, music that was a key element for Eisenstein film editing theory and principles of connecting image and sound. The books are not only in Russian, but in English, German and French that Eisentstein could speak fluently and what helped him to travel abroad.
