The game of Great Guns! was published by Jaques around 1920. It’s a memory game where players attempt to guess and call out their opponents cards as they reveal cards in turn. They must precede any call with the words ‘Great Guns!’. This pack of 47 cards, is one short as there ought to be 12 sets of 4 cards giving 48 in total. It is in the original box but there are no rules.
