Check out this auction. World's Largest Slot Card --- It is huge measuring a whopping 4 1/2" x 6 3/4" - almost 4 times the size of a regular slot card. Obviously this card will not fit into any slot machine - it was made as a sample to show-off the quality artwork. This would be a cool addition to your collection. Don't believe what they say - SIZE DOES MATTER, bid today and good luck!
