Located above the glass bas-relief Youth Leading Industry, this large polychrome-painted limestone cartouche shows two monumental-sized figures symbolizing the basic trades of the nation. The male figure represents commerce, while the female figure symbolizes industry. The large caduceus, placed between the two figures, is a symbol of Mercury, god of trade. Attilio Piccirilli sculpted idealized, superhuman figures, reinforcing the concepts of divinity and patronage and by applying them here, conceptually elevated the worlds of industry and commerce.
