Portrait of Pierre and Marie Curie. On their left in the background is represented a bulb containing radium salts photographed thanks to their only luminosity. Reds reproduce the graphics drawn by Marie Curie in her study on the probability curves relating to the action of X-rays on bacilli. At the top of the watermark, “les petite Curie”, radiological cars that circulated on the initiative of Maris Curie during the war of 1914-1918. Under the small triangle intended for the visually impaired, are printed four round figures symbolizing the so-called “subatomic” world.
