German Rounds, Op.25 (Moszkowski, Moritz)

[TobisNotenarchiv]

I checked the file [[German Rounds, Op.25 (Moszkowski, Moritz)|German Rounds, Op.25]] for lacking publisher data and found:
German rounds. Opus 25 for piano duet. New York: International Music Company 1983 [Plate number 2548]. (Edited by Marthe Morhange-Motchane).

Is this file then really public domain? Marthe Morhange-Motchane as editor died 1996.

This might have to be taken down. I'll have a look.
