The post was started at Brooklyn, New York, (United States of America), and the service changed hands several times over the next few years. During this period the service operated under diffrent names, and the proprietors all issued their own stamps. The original service was short lived and stopped operating about 1845. Very soon after this, Welling Walton, (who was probably Boyd's agent), started the post again as Walton & Co's City Express.

In 1847 Walton sold the post to Henry Kidder, (who also ran Kidder's City Express Post in Brooklyn). Over the next few years the service changed hand on more than one occassion.

At some time around 1851, stamps were issued for the post. These consisted of a one cent value printed on blue or green paper and a two cent which was printed on crimson, pink, blue and orange papers. All the stamps were printed in black.

          

The 2 cent on pink also exists on unsurfaced paper which was coloured right through.

Two stamps were issued for the service. The 1 cent, in black had the inscription at the top, 'BROWN & Cos' and was lithographed. There is no known explanition for the variation in spelling. The 2 cent value had the correct spelling of the inscription on the stamp.

It is not know exactly when the post closed down, but it appears to have operated for at least two years under Browne's management. It is unlikly that it operated after 1860.

The first primitive stamp issued was a type set 2 cent value. This was printed in black on red glazed paper. The design showed the name of the service, (in three lines), with a line below the last line of text. Below this the value was inscribed, (in word) and the whole was surrounded by a single lined frame. A later version, which was also printed in black on red glazed paper, showed a similar design but with an ornamental frame.

Later a 2 cent engraved stamp, printed in black on white paper was issued. This showed a portrait of George Washington.

A one cent stamp was issued for the service which was printed in black. The stamp was printed on bright red, violet, yellow, vermillion and green papers. The design showed a man pushing a trolly loaded with a mail bag with the inscription 1876 above the bag. This was enclosed in an circular frame with the inscription 'FROM BROWN'S STAMP DEPOT - 145 NASSAU ST., N.Y.' The inscription 'CITY POST' appeared at the top of the rectangular outer frame with 'ONE CENT' at the bottom.

A bogus version of the stamp is known and this shows the devil behind the trolly pusher. The inscription on this bogus stamp has also been altered.

During this period of independence it issued its own stamps, the first of which appeared in 1852. On the 1 January 1868, their issue was superseded by the issues of the North German Confederation.

The first series of stamps consisted of 1, 2 and 3 silbergroschen values. The stamps were typographed by Johann Heinrich Meyer from wood engravings made by Carl Peterson, (a native of Brunswick). These stamps were printed on yellowish-white paper in sheets of 120, (12 x 10) and were issued on the 1 January 1852.

In 1853, stamps of the same design were intoduced which were printed in black on various coloured papers. Values of a quarter and a third silbergroschen were first introduced and these were intended for internal mail only. Between 1853 and 1856 the 1, 2 and 3 silbergroschen values were also printed in black on colored papers.

In March 1857 a 1 silbergroschen stamp was produced in four sections, each of a quarter silbergroschen which could be divided and used on internal mail. The issued stamp was printed in black on brown paper. The original version, which was prepared but never circulated was printed in brown on white paper.

In 1893 Liberian registration stamps bore the letter 'R' along with the individual names of the five principal postal areas, (of which Buchanan was one). Later, sets of registration stamps bearing the names of each city were released.

In 1903 the set portrayed President Gibson. The 1919 series, which was in a triangular format showed a seascape and this format was maintained for the 1921 issue.

In 1877, Samual Archer King made a number of flights in the United States of America. On at least one of his flights he carried mail and for this service a special stamp was issued. The stamp was a 5 cent value in blue and were designed by John B Lillard, and engraved by J H Snively. Produced at Nashville, Tennessee, the stamps were printed in sheets of 20, (2 rows of 10). The upper row was printed inverted in relation to the lower and tete-beche verticial pairs are known.

On the 18 June 1877, King and six companions went up in the balloon from Nashville, taking a bag of mail with them. They decended at Gallatin after a 26 mile flight and the letters were posted. The letters, in addition to the 5 cent balloon post stamp, also bore a 3 cent US postage stamp. In all known cases the postage stamp was cancelled in the normal manner whilst the balloon label was left uncancelled.

The first issue was made on the 1 January 1882. This consisted of a 2 kopek which was printed in blue. This lithographed stamp showed a large numeral in the centre enclosed in an oval frame. This was then surrounded with an upright rectangle with the numeral repeated in each corner.

In February a similar issue was made but with the size of thew stamp reduced. This was followed in August by a further reduction in the size of the stamp.

These issues were used in the territory known as the Netherlands East Indies, (except for Java and Madura), until 1912 when they were discontinued.
