Thank you!!! I just received yesterday the 1971 Venus airbase issue (that's on the back cover) -- a great futuristic, inspiring, barely known project (discussed here where I discovered it first). I also got a very rare issue, issue #3 from 1938, "explaining" weightlessness with many drawings. Do you also have weirdy stuff from the 30s too? Also, I'm a keen watcher of "Priroda i Liudi", in which interesting articles or short stories were published in the early 20th century.
