A rectangular bronze plaque, securely mounted on a red brick wall, presents the name and founding date of the American Philosophical Society. The plaque's background is a dark, textured surface, contrasting with the raised, bronze-colored lettering that spells out "AMERICAN PHILOSOPHICAL SOCIETY" in three lines. Below, it states "FOUNDED 1743". The plaque itself is bordered by a thin, bronze frame that complements the lettering. The surrounding brick wall adds a sense of history and permanence to the image.
