2 deck set with custom art

From the 'World of Playing Cards': Five Suit Bridge was invented in Vienna in 1937 by Walter W. Marseille and Dr. Paul Stern. At a time when cricket, chess and bridge were popular social games, special 66-card decks went on sale in the UK manufactured by De la Rue and Waddington’s with the fifth suit as crowns (called “Royals”). However, because the game was complex it proved to be unpopular, they were withdrawn in 1939 and have been forgotten.
