Song of the Volga Boatmen

Copyright 1926 but published in 1933. I love the simple yet graceful black and white line on this cover and the use of solid black. The final image is the Morris logo from the back cover, it appears to be from an earlier era and has a crowded look to it.

I can detect a faint "M" in the lower corner, the only clue to the identity of the artist.
