Original wrappers uncredited but designed by Russian artist Alexandra Exter (1882–1949) featuring an abstract depiction of Soviet dancer Vera Drutskaya (1898–1946), whose choreographer was Kasyan Goleyzovsky (1892–1970).  One of 3000 copies.  With a list of Milyutin’s works on the last page.  Signature "Maria d'Arto" (in Cyrillic) in ink to title.  10.25 x 13.75 inches (26 x 34.9 cm).  Goleyzovsky was a an avant-garde choreographer creating acrobatic routines; Drutskaya excelled in such.  Milyutin is probably the only composer in this collection whose career was not affected by Stalinism; he won a Stalin Prize of the Second Class in 1949.  Maria d'Arto (stage name; real name was Mariya Aleksandrova) was a ballet dancer who enjoyed success and popularity in Russia before and after the First World War.

(g) Mayman, Zinovy Aleksandrovich. (1902–1991).  Yevropeizirovannaya Yevropa (Europeanized Europe), choreographic sketch "from the repertoire of a mobile theater."  For piano.  Petrograd: self-published ("izdaniye avtora"), n.d.  Unbound folio.   4 pp.  Original wrappers designed by Russian artist Vladimir Izenberg (1895–1969), depicting a couple of Europeans in formal attire reaching for each other and, in between, a grinning African (probably African-American) in minstrelsy attire, holding the man in his right and the woman in his left hand.  Dedicated to N. V. Petrov.  One of 500 copies.  Handstamp of Fischer music store, Petrograd, to title.  10.75 x 13.75 inches (27.3 x 34.9 cm).  Worn, torn and stained, with some early professional repairs.  The name "Petrograd" allows to date this edition no later than 1924.  Even without the title art, which is frankly racist, it would be clear that the title of the piece is ironic, as the music is a foxtrot. Vladimir Izenberg was the son of the much better known sculptor Konstantin Izenberg (1859–1911).
