This 2-cent red commemorative stamp from the United States was issued in 1929 to celebrate the Golden Jubilee of the Electric Light, marking 50 years since Thomas Edison’s breakthrough with the practical incandescent lamp in 1879. The design prominently features Edison’s original bulb, with elegant scrollwork and inscriptions honoring the milestone. Printed in a rich carmine red, it is a classic example of early 20th-century U.S. commemoratives. Postmarked examples like this remain popular for their strong thematic appeal in science, technology, and innovation collections.
