What do such disparate contraptions as the sewing machine, the folding umbrella or the hot air balloon have in common?
Once again stamps are happy to provide answers to those of enquiring minds and I have to thank Roland for sending me a cover with a stamp that led me to a possible answer. Un grand Merci, mon ami.
According to la Poste, they all are French inventions; same as the calculator, cinema, soundtracks, radio and the digicode, although I am sure that such an assertion, in some of the cases, must be opened to discussion...
The above mentioned eight inventions were highlighted in a self-adhesive, "Lettre Internationale" stamp set issued as a carnet on 16JUN2025.
One of these stamps, the one featuring the hot air balloon, was used on this particular cover.
It is well known that the principle that governs hot air balloons had been in use long before Pilâtre de Rozier and Laurent d'Arlandes rose to the sky in Paris, in 1783, aboard an unthetered hot air balloon designed by the Montgolfier brothers, for it is, of course, the same principle that was used in sky lanterns in ancient China and other parts of the Eastern hemisphere.
I wouldn't also be a decent Portuguese if I were not to mention the experiments of my fellow countryman and Jesuit priest Bartolomeu Lourenço de Gusmão who, in 1709, proved the feasibility of the concept of manned hot air ballooning, with a demonstration of his flying apparatus, which he called Passarola and in which he would actually later actually ascend (and descend, hopefully.... :-)), as stated in an article dated of October 1786, in the London Daily Universal Register.
For the purpose of this article let us though assume that the first fully functional hot air balloons for practical human flight were those of Joseph-Michel and Jacques-Étienne Montgolfier, who would lend their family name to their invention - the Montgolfière - the subject of the stamp on the cover.
The stamp was cancelled with the pictorial postmark of the Service des Oblitérations Philatéliques, located in Boulazac Isle Manoir, a commune in the Dordogne department of south-western France.
