Schumann Violin Concerto (FPE/Schott) - public domain?

[Bhm]

As far as I know, the first published edition (full score) of this work was issued by Schott in 1937. I am assuming that this is an Urtext edition, but since the editor, Georg Schunemann, died in 1945, this should be public domain in any case based on the life + 70 years rule.

Unfortunately, matters may be more complicated than this because Schott renewed the copyright in 1965. I still can't see how this can cause the copyright beyond 2016 (again, life + 70 years), so then the question becomes - what effect does copyright renewal have on the year that a publication enters the public domain?

Copyright renewal registration in the USA only affects the USA copyright status. The fact that Schott renewed the copyright entry 28 years after first publication means that the full USA copyright term of 95 years from publication applies to the edition. This means that the edition is only guaranteed to be in the USA public domain in 2033 at the earliest.

However, since the editor, Georg Schünemann, died in 1945, this puts all his compositions and contributions to edited scores in the Canadian and EU public domain (which both apply a life + 70 years copyright term) which includes this 1937 edition of Schumann's Violin Concerto.

Therefore, if you possess a copy of this edition, you are welcome to upload it to IMSLP, as it is in the public domain in Canada and the EU.
