Winged samaras on the Moon. J. Miltenov.Illustrated by Nikolai Mirchev. Sofia: Bulgarian Artist. 45 p. 30 cm, 1970.
I am sure that is not the title but the google translate options does not work well. Here is what the seller typed:
"Курносик на Луне"
Samaras are a one-winged seed, like a maple seed. Feel free to give me a more correct title in the comments.
A readers comments: "Курносик на Луне"... "Курносик" is a boy's name (surname or nickname). For example it means he has a snub nose."
It is a fictional story really only by the inclusion of a cosmonaut smaller than a lady bug. :)
This is on of the stranger illustrations I have seen in these books. I wish I knew what the story says at this point.
