Don't have a catalog handy, so can't suggest a number, but I'd guess early 20th century Russia. 50,000 ruble value suggests it was printed during a period of high inflation, as occurred during WWI, through the Great October Revolution and into the Civil War period.
Semi-official stamps/vignette. Something like the Soviet ODVF air fleet stamps & labels from different localities in Russia from 1923.... Some could of been used for postage circa 1923-24 in certain cases.
