Commemorative or promotional French stamps first appeared in 1923, finally ending a 74 year onslaught of 184 definitive postage stamps.
France actually did pretty well in coming up with their first
commemorative stamp issue. As far as the first stamp issuing countries
go, the United States had a two year head-start on France, and they had
issued 229 definitive postage stamps, before issuing their first
commemorative. Many of the European kingdoms did not issue any commemorative stamps at all, during their existence.
I know, the 12 stamps shown above have that "definitive-letter-postage-stamp-series" look to them. THEY ARE, AND THEN THEY ARE NOT!
The 10 Cent., 30 Cent., and 50 Cent. denominations, shown above, were issued at the beginning of 1923 to commemorate the 100th Anniversary of the Birth of Louis Pasteur on December 27, 1822.
They were popular, and their use continued for some time as regular definitive postage French stamps. The other denominations in this set were issued between 1924 and 1926.
Louis Pasteur (1822-1895) was a French chemist and microbiologist. He is famous for his breakthroughs in the causes and prevention of diseases. He is best known, though, for the invention of the process used for treating milk and wine to stop, often deadly, bacterial contamination. Today, we call this process "Pasteurization"!
On June 15, 1923, the Merson Type 1 Franc definitive stamps were overprinted CONGRESS PHILATELIQUE / DE / BORDEAUX / 1923, in blue, to promote the International Philatelic Congress being held there. An example is shown above, at the left.
On October 6, 1924, the stamp shown above, at the right, was issued. It commemorates 400th Anniversary of the Birth of Pierre de Ronsard (1524-1585), a medieval French poet. During his lifetime, he was called the "Prince of Poets" by his contemporaries.
The set of four stamps, shown above, were issued on April 1, 1924 to promote the upcoming 8th Summer Olympic Games. The Summer Olympics were held in Paris, from May 4, 1924 to July 27, 1924. These colorful and modernistic commemorative stamps depict .....

The set of six stamps, shown above, were issued during 1924 and 1925 to promote the upcoming International Exposition of Modern Industrial and Decorative Arts. The exposition was held from April to October 1925 in Paris. The term "Art Deco" originated at this exposition, being a contraction of the French words for the exhibition, "Arts Décoratifs".
These stamps utilize four different designs, repeated throughout the set. They are:
The massive souvenir sheet, shown above, was issued May 2, 1925 for the International Postage Stamp Exhibition. The actual size of the sheet is 140 mm x 220 mm.
The exposition was held in Paris, during May 1925, and these souvenir sheets were only made available for purchase at the exhibition, which would surely account for their rarity today.
The central feature of the sheet is a 5 Fr. denomination block of four of the Sage Type definitives, printed in Carmine. Of course, everyone that collects the Sage Type French stamps needs one of these 5 Fr. stamps for their set. As a result, many of these 5 Fr. stamps were removed from the souvenir sheets and saved as single stamps. Many of them were actually used for letter postage! The single stamps that have been separated from the souvenir sheets are actually pretty common.
