Semaphore Signaling: Historical Flag Communication Method #17234 (License: Personal Use)

This black-and-white line drawing depicts a uniformed signalman standing upright, arms raised high, each holding a distinct semaphore flag-one solid black, the other with a crosshatch pattern-to convey coded messages. The figure wears a peaked cap and buttoned tunic, reflecting military or maritime signaling practices from the 1800s. Such visual signaling was vital for naval operations, railway coordination, and battlefield communication before radio.
