Jax Ltd., of Minneapolis, has published a playing set for the card game Kings in the Corner since 1996. The actual card game, which is simply multi-player solitaire, was invented by "the Grey family aboard the S.S. Suevic, in the 1910s" according to a current Wikipedia entry. Whoever invented the game, it is a longtime family favorite. And the Jax set provides a convenient tray for holding the cards during play.
