Unfortunately I do not consider it to be possible to put my signature beneath the version of obituary notice about Revol’ Samuilovich Bunin, which was sent to me, as from my opinion what I received for signing is exactly an example of coldness and conventionalism what the editors themselves asked me to avoid.
Yours sincerely,
M. Kuss
