After using overprinted French stamps, Lebanon began issuing its own stamps. The firsts beared Grand Liban, shortly changed to Republique Libanaise, see the error part to view some of them.
Here we have the most two important stamps of the mandate period and in all Lebanese period. The 2 stamps come from the well know pictorial 25p issued in 1926, this stamp together with its set has been overprinted several times. The two rarest overprints are the air ones where only a very small quantity have been issued. Beware of forgeries, even used. Spectacular...
Here you have the two nice high value stamps from each set. They are basically landscape sets.
A very rare and high value stamp. 500 piastres at its time was a big sum sufficient to send a registered parcel to USA. Also the overprint here is important. It is the independance day of Lebanon in Arabic: 22 November 1943. It represents the day where the presidents of the Republic, the prime minister and other ministers had been liberated after being jailed by the french forces.
This stamp issue date is 1945, theoritically it is after the independace. But it is listed before the big issue of independance. It is a nice tax stamp representing the museum of Beirut. It was destroyed and robbed during civil war, and its reconstruction and rehabilitation did not finish yet.
Nice scan where you see different used Lebanese stamps from the mandate periods. The point is that all are nicely canceled by different Lebanese towns other than the Capital Beirut. Most of the Lebanese stamps were used here, the politic, administrative, touristic, financial... capital of Lebanon. Town cancels include cities or villages of Jounieh, Nabatieh, Rachaya, Saida, Zghorta...
Postage mandate stamps were also used for fiscal purposes by overprinting them. Then special fiscal stamps were used. You have some errors in the fiscal overprints like that shown there. The third bottom stamp has "droit frscal" instead of "droit fiscal". The point to stress is that there errors were 100% unintentional, so they must have a good value.
