Two Arm Semaphore + Morse Code 1914 Pocket Signal Disk early alphabet sampler I couldn't resistI've had a few different versions of "Pocket Signal Disks" along the lines of this one, and will always grab them when I find them as who knows when knowing morse code and semaphore might come in handy???
