In 1949, France organized an international philatelic exhibition to commemorate the centenary of the French postage stamp. The exhibition was held in the Grand Palais in Paris from June 1 to June 12, 1949.
In addition to a special stamp (not shown) issued for the exhibition, vignettes, also known as poster or cinderella stamps, were issued without value. A total of twelve vignettes were printed reproducing the exposition’s poster. Each day a vignette with a new color was printed.
The vignettes were offered to visitors who received the vignette for the day of their visit plus a vignette of the previous days.
