This is an issue for Belarus, but the Michel catalogue calls it a private fake stamp. It is mentioned there in the chapter about "Russland - Post der Buergerkriegsgebiete 1918/23" (Russia - Post in the territories during the civil war 1918/23).

#1. "White Russia". In 1940 they were listed in Stanley Gibbons' catalogue as follows:
WHITE RUSSIA
Type 1. Designed by R. Sarinsch and printed at the Latvian State Printing Office, Riga.
1920. Type 1. (a) Imperf. 1) 5k. green; 2) 10k. scarlet; 3) 15k. violet; 4) 50k. blue; 5) 1r. brown.
(b) Perf. 11 1/2. 6) 5k. green; 7) 10k. scarlet; 8) 15k. violet; 9) 50k. blue; 10) 1r. brown.
The 15k. varies in many details from the design of Type 1. It is doubtful if these stamps were ever used for postal purposes.
(Stanley Gibbons priced mint stamps 1 or 2 pence each).

By 1974, Stanley Gibbons' position had changed, thus:
WHITE RUSSIA
Stamps in the above type, 5, 10, 15, 50k and 1r., both imperf. and perf. were prepared for use by a force raised by Gen. Bulak-Balakhovitch in 1920. We have never seen genuinely used copies and have no evidence of their issue.

The following information is from the International Encyclopedia of Stamps, vol.6, pp.1964-65, (c.1972).

An independent Byelorussian state was pronounced in March 1918 by an administration in Minsk known as Rada, but it existed only for nine months until the establishment of the Byelorussian Soviet Republic. The military administration of Rada, known as BNR (Byelorussian National Republic) [This is the inscription at the foot of your stamp] lasted for several decades. The short-lived Rada government in Minsk issued three stamps in 1918 [These are the three illustrated as Weird Stamps Nos.296, 294 and 295 respectively]. The special section (Asobny-Atrad) [This is the inscription at the top of No.1] issued five stamps in Riga in 1920 for use by troops under the command of General Bulakh-Balakhovic in the region of Dzvinsk. Although these stamps were regarded for a long time as private speculations, there is evidence that they were postally used through the assistance of other administrations, including Latvia, which recognized the republic. During the 1971 British postal strike the Association of Byelorussians in Great Britain organized a private postal service and issued its own stamps. It also used some of the 1920 BNR stamps, surcharged ZBVB POST and the value, 10p.

This item has a much more debated life. Let me quote :
"A. Rosselevitch, in the 8th issue of the Journal of the Russian-American Philatelic Club, Nov. 1963, described this issue as follows: "A series of stamps of large size (26x33.5 mm.), with the inscription "Absobni Atrad B.N.R." which means: "Special Troop of People's Republic of Belorussia"; 5k.green, 10k.red, 15k.violet, 50k.blue and 1R.brown, both perf and imperf. Some of the stamps in this series are found cancelled with a stamp with inscriptions in White Russian language, or with completely fantastic cancellations. There was a tale spread about these stamps that they were issued by Bulakh-Balakhovitch in 1919 or 1920 when he appeared in Belorussia after the fall of the NorthWestern Army of Gen. Yudenich. All these rumours have caused great doubts among collectors but we think is still correct to classify these stamps as private fantasies".

A somewhat different story is told in the Rossica Journal by W.Lesh in an article entitled "Balachovka, the Asobni Atrad Issue of the B.N.R.". The activities of Stanislav Nikadzimav Bulak-Balachovic are outlined as he rose through the ranks to Colonel under General Rodzianko, set against a backcloth of the military activities of the White and Red Armies, with the frequently changing front in Belarus, and the corresponding North Western Army and OKSA stamp issues".

Duarte, Sanchez & Mella were three famous men in Dominican Republic history. This is not a postage stamp as it has no country name inscribed.

I have two different denominations of this stamp. It is definitely a revenue stamp. Not in Forbin of course because it is from the 30's.
Brian McGrath

This stamp is probably a fiscal stamp because the three figures in the middle are images of old Chinese money.
Anton Haddeman

Blue Chinese postal savings definitive stamp. The two central characters mean (read from right to left) the figure "10" and "dollar". So it just means 10 dollar like the value tablet show. This stamp shows coins of the Chou Dynasty, printed in typography by Central Trust in Chungking and issued in 1944. Perf. 13. The series is 6 values: 50 c. grey, $1 green, $2 brown, $5 red, $10 blue (stamp shown) and $20 orange.

This is definitely Egypt.

This is a complete set (as far as I have information about it) of the Manchukuo Postal Savings issue from the period 1932-1945.

Andrew Freeston

This is a postage stamp from Iraq, commemorating the second anniversary of the revolution. It was issued on July 14th, 1960 and is listed in the Michel catalogue as #298.
Hans-Joachim Böckenhauer

The stamp pictured is most likely from Turkey; the tughra and crescent combination is the clue. The inscription "Timbre" usually indicates that it is a fiscal or revenue issue, i.e., a tax stamp.
Smokey Stover

These are most likely revenue stamps. They are from Japan.

#10, and #10A are Japanese Revenue Stamp, #10 is for document stamp and #10A is the income stamp.
