English: This is the Asian portion of an old map of the world (a Mercator projection on a plywood backing) that my old roommate's mother used when she was a schoolteacher. Judging by its inclusion of Manchukuo, and the Transcaucasian Republic in the USSR, this seems to have been made somewhere from 1932 to 1936. Note its inclusion of Tannu Tuva northwest of Mongolia (though it's inaccurately drawn--it's backwards!). The tack may have been intended to mark the location of Novosibirsk.
