Two young women with symbols of manual labor (a shuttle and a washboard) place a wreath around the cameo of Alessandro Volta to indicate their gratefulness for the electricity that liberated them from menial tasks. The poster is for an exhibition of electrical products being held in honor of the 100th anniversary of the birth of Volta, the inventor of an instrument for measuring electricity (voltmeter), and the man who defined a single unit of it, a volt, as "the electron drive force which, when applied to the conductor with the resistance of one ohm, produces a current of one ampere.” That so impressed Napoleon that he made him a count as well as a senator of Lombardy. This is the smaller format.
