Austria With Cyrillic Cancellation? (Sc 35, MI 36iia)

Any ideas about this? Is the Cyrillic an overprint? What would it mean? There are two CDS cancellations, one of which could say Wien, but are they over or under the Cyrillic?

It's not from Austria, it's from the Austro-Hungarian Empire. Some of the eastern parts of Austria-Hungary used the Cyrillic alphabet: for example, any of the Serbian-speaking portions. (Generally, Austro-Hungarian stamps are worth more when cancelled outside of Austria.)

D.TS. in Cyrillic script stood for dozvoleno tsenzuroy /= censored/ in Russian and used to be rubber-stamped on mail during WWI in Russia.

It is most strange to find this rubber stamp applied on an old kreuzer-denominated stamp issue like that.

Thank you, both. I had known that in the Banat region of the Empire the Serb population would have used, or at least been familiar with, the Cyrillic alphabet. But I knew of no local authority there to stamp or overprint Imperial mail, let alone the meaning of those Cyrillic characters. Florian explains both their origin and meaning but also raises another question. The stamp was issued in 1867, long before WWI. Why then is mail, postmarked Vienna, censored in Russia, or at least in Russian controlled territory? Was it a letter to a prisoner held by the Russians. The Crimean War had ended in 1856, a full eleven years before the earliest uses of this stamp. And the Austro-Hungarian regime was involved only peripherally in that war. So still I wonder; why is Russia censoring mail franked with this Austro-Hungarian stamp?

Bogus overprint?
The stamp was withdrawn in 1884.

Found this extensive exhibit of mail censored by Russian authorities during WWI.

Confirms Florian's translation of the Cyrillic on my stamp, as well as its function. Reading the Intro to this exhibit, and remembering that my stamp appears to have originated in Vienna, I now think it possible that the letter it franked went to Russia, or Russian controlled territory, from anyone in Vienna, of any nationality, civilian or not. Russian military authorities seem to have reviewed all such mail—at least during WWI. But this stamp was issued 1867 and was only valid, as Vayolene says, till 1884. Not clear whether such censorship of foreign mail was practiced at this early date, or whether the overprint is genuine.

The censor marking above started in 1873,so; same time period.
Postal censorship dealt only with foreign newspapers and magazines arriving from abroad as printed matter and some letters with printed texts. All other publications including books, advertisements, pricelists, music with words and so on were to be redirected for examination to the Committee of Foreign Censorship, which in the early 1890s was renamed the Central Committee of Foreign Censorship.

Thanks, perf12. Actually, the exhibit I found features censored mail only from 1904 to 1917. Glad to learn when the practice began: within the period when my stamp could still be used.

Once again, a fairly common stamp with uncommon interest and therefore value, albeit not monetary. But if it were money I was after, I'd be doing something other than collecting postage stamps of the past.

The stamp is scarce with that marking.IMO

Even better! Found in an APS circuit book for next to nothing. It often happens that sellers there pay little attention to cancellations and other marks of this sort.
