As soon as American manufacturers discovered that card players considered the odd card of value, the Joker was quickly represented by various grotesque figures, that differ in every pack, and are somewhat confusing to players. It, therefore, seems a pity that a uniform design is not agreed upon, as is the case with the court cards. Any deviation from the dress of the figures on the latter meets with instant opposition from players. It seems peculiar that the card is never represented by Mercury, or a fool, or a clown, or perhaps, a red devil, which would make it easy to distinguish from the Ace of Spades, which is often, and sometimes disastrously, mistaken for the more powerful Joker. The most desirable image that might now be used would be a reproduction of the beautiful flying figure of Mercury, carrying the caduceus, by John of Bologna. No French packs, and very few English ones, contain a Joker, since the games that call for its use are not favourites in those countries. However, the Joker, with all its inherited value, is known in the Japanese and Korean packs of cards, where it seems to be of sporadic growth, and is apparently not connected with the ancient god, Mercury, the quondam ruler of the cards. Nor are the makers of the French packs wedded to one costume for the court cards, as are those of England, where the slightest change in the dress, emblems, or colours, causes a remonstrance from players, who insist on retaining everything as they have been accustomed to it for several hundred years. The English people, however, do not reverence the images because they are those of their own royal families, for it remained for an American to identify the origin of the pictures, and to connect them with the originals. English players even resented the alteration made about 1870, when the cards were cut in two, and reversed, making what are known as "double headers." These are sometimes declared to be an American innovation, but in "Cartes a Jouer," by M. Merlin, a pack of Venetian cards, dated 1602, is illustrated, the court cards of which are so divided. Another novelty invented and introduced in America, is the "index," or the number of the card printed in the upper left-hand and lower right-hand corners. This was necessary for playing Poker, where the players keep the cards squeezed together as closely as possible, to prevent other players looking into their hands. These useful little numbers have given their name of "squeezers," or "indexed cards" to this fashion. English clubmen, however, absolutely refused to adopt cards printed in this way. The costume of the King in English and American packs is a grotesque reproduction of that of Henry VIII of England, and that of the Knave is like the dress of the page of his day. The long sleeves were nicknamed "pokeys," since food or precious articles might be concealed in them, so these bag sleeves were the ancestors of pockets and reticules.
