Semaphore Signaling with Red-Yellow Flags - Visual Guide #304292 (License: Personal Use)

This illustration depicts a standard semaphore signaling posture where a person holds two flags-each diagonally split red and yellow-to transmit coded messages. The flags are positioned at distinct angles: one held horizontally and the other diagonally downward, representing a specific signal in standardized flag code systems. Such signals are historically used in naval operations, railroads, and airfield ground control.
