The Dwarf motif used on the card back was commonly employed in a wide array of other Snow White toys and products that year in conjunction with the film's North American theatrical re-release.
The deck consists of 55 playing cards: 5 of each Dwarf, 5 Princes, 6 Queens, 8 Mirrors, and just 1 Snow White. An additional 5 promo cards for other games were also included in the box.
The winner gets to turn over the Snow White card at game's end and wake the Princess.
