Aux amateurs de physique - Public domain book illustration

French cartoon shows people crowded outside the Tuileries Garden wall in Paris to view the first balloon ascension of Jacques Charles and Marie-Noël Robert in 1783. Several people are climbing over the wall, including two women whose dresses are pulled up exposing their naked bottoms to spectators who stare at them instead of the balloon aloft in the background.
