"L'album des demeures d'Hypnos" is a lithographic work by Man Ray that explores the dreamlike realm of Hypnos, the Greek god of sleep. Created through the lithographic process, the composition reflects Man Ray's surrealist sensibility and his interest in depicting the ethereal and unconscious imagery associated with sleep and dreams. The work exemplifies Man Ray's experimental approach to printmaking and his ability to translate surrealist concepts into visual form.
