Invented at the end of the 18th century and used as a pragmatic purpose and an attraction for expositions throughout the 19th century, the balloon enthusiastically enthused people as a realization of the dream of flying in the sky of mankind, admiring the age of all-around science. It became a symbol. In this charcoal painting, produced in 1883, the balloon is shaped like a light bulb, which has gradually become widespread throughout the city of Paris since the late 19th century. The image illuminated inside the sphere is a profile that symbolizes the light of Kaimei.
