This oil-on-canvas portrait shows Benjamin Franklin in a relaxed pose, head slightly turned, eyes direct. The canvas is about 28 inches tall and 22½ inches wide. Duplessis—who painted the original while Franklin was in Paris—keeps him simple and grounded: no wig, plain jacket. The background is unadorned, letting the figure stand alone. A brushstroke here hints at the canvas’ texture, while the warm undertones give a soft glow to his face.
Duplessis based this version on an earlier 1778 work; the artist used similar lighting and scale. The painting has long appeared on the American $100 bill, connecting it to the currency people know today. Franklin was a signer of the Declaration and later petitioned Congress for slavery’s abolition. Duplessis captures him as a “man of the people.”
