This French postage stamp belongs to the classic "Type Sage" series, first issued in 1876. It features allegorical figures of Peace and Commerce, symbolizing harmony and prosperity, designed by Jules-Auguste Sage. Printed in blue, it carries a 15 centimes denomination, a key value in the series that saw extensive postal use during the late 19th century. The overprint and circular cancellation add historical postal character. Highly collectible, the Sage issues mark an important transition in French philately after the Ceres and Napoleon III designs.
