Shostakovich’s score of his Seventh Symphony, autographed and inscribed twice:
To dear Boris Emmanuilovich Khaikin, as a mark of my heartfelt thanks and good wishes, that your talent and skill continue to flourish. D. Shostakovich. 10/VI/1943 Moscow.
P.S.: I am writing these lines with great pleasure after your wonderful performance of this symphony on June 22, 1943. After this concert my idealized gratitude became real gratitude, and there is literally no end to my delight. A huge thanks. D. Shostakovich
