During the height of the craze for the card game bridge, in the mid-1930s and afterwards, card manufacturers developed slightly narrower decks of cards. These were initially known as "bridge decks," and they developed because, in bridge, players must hold a large "fan" of cards in their hands. Narrower cards made this easier to do. Also, makers soon learned to package two decks in one saleable box. The two sets of partners at a bridge table could therefore shuffle one deck while one hand was played. Two decks sped up the game and, naturally. the manufacturers could charge more for double bridge decks. Today bridge is not quite as popular as it once was, but narrow decks are still produced and often packaged in pairs. Here an angel theme makes a double deck a tempting holiday gift.
