The other day I came across the following dedication in a library copy of
Rimsky-Korsakov's songs op. 50, written in Russian in black ink:

   To the talented, wonderful artist
   Anna Samoylovna Eltur
   in good memory
   N. Rimskaya-Korsakova
   21 May 1913.

I consulted several handbooks, but could not find the name of this artist.
Another copy on the same shelf was stamped in (Latin characters):

   Anna El-Tour
   Odessa
   Preobrajenskaja 45

Can anyone supply information on this singer(?)?

By the way, would this book, as it contains a written inscription by the
composer's widow, be of any value as a collector's item?
