Rare American Flyer No. 577 Ringling Bros. & Barnum & Bailey "Greatest Show on Earth" billboard flasher by A.C. Gilbert (1946–1950), in an eye-catching green and white metal housing. Features incredibly vibrant, sharp lithograph—miles ahead of typical wear—on a 7½″ × 5″ base. Includes light fixtures, wiring, and original button. Untested (sold as-is), but highly displayable or perfect for restoration. Ideal for collectors of vintage toy trains and circus memorabilia.
