A bit of prolog/epilog to those 1939 New York Fair U.S.S.R. reissues:

Most, if not all, of the singles were originally released on the Noginski Zavod label; as were the Soviet movie scores/soundtracks reissued by Stinson Trading Co.

And within a year or two they all ended up on The Music Room's International Series, Set 103, released on Eric Bernay's Keynote label.

Both Keynote and Stinson repackaged some of that yet again as albums and still more singles. Odds are good the Noginski Zavod originals were already in Charlie Stinson's bargain bins before 1939. The American dubs could have come from the records or the films.

Just a reminder, Stinson Trading Co. publicist/liner notes author Noel Meadow was also the American agent for Artkino.
