By the way, I collect Russian/Soviet badges (znachki), and
I have a very nice one that honors Vavilov.
It has his image, the dates 1887-1987, and the name N.I. Vavilov.
It is in the Russian language of course. I can scan and send an
image of this wonderful badge to anyone who is interested in seeing
it.
