Blue (card backs have purple hue) version of this 5 suit playing card deck from USPCC where the 5th suit is an eagle. In 1938 there appeared a five-suit deck, having the usual 52 cards of the standard deck plus a complete fifth suit. In the United States this fifth suit was green, called EAGLES, and marked by an appropriate symbol; in England it was blue, called ROYALS, and marked by a crown. A five suit Bridge game was widely played for some months, but was soon forgotten. Five-suit poker made a better game, but can seldom be played today because the cards are no longer generally on sale. Morehead, Albert H.
