While cards were taxed and the tax stamp often appeared on the ace of spades because it was the first card in a package, this does not mean to suggest that only the ace of spades was taxed.

"Not playing with a full deck" is a modern phrase like "a few beers short of a six pack" or "A few sandwiches short of a lunch bucket". Louise Graybiel 7-6-2004
