Flip Cards International Code Flags
Each card shows a flag of the International Code in colour on the face, with the signal letter or number and the meaning of the signal flag on the back. The phonetic spelling of the letter is also shown, making the set doubly useful. Although no longer required by some yachting authorities, professional seamen and navies still need a knowledge of flag signals. Also in the set is a useful instruction card.
There are 41 cards in the pack.
