Sunset Press © 1940s, International Signal Cards, complete set, as used by ships and planes in World War Two.  These items were available to our Navy and handed out with the Blue Jacket manual to the sailors or anyone else with a need to know.  Has the flag definitions, radio code names, Morse code, and Semaphore info.  The cards are in nice condition, rarely used.  The box, on the other hand, looks like it's been in someone's pocket for a while, w/ stain, tear, staples.  An interesting piece of history, still relevant today.  Thanks for looking.       xxxx-1305-45  85/30
