How many eyes are in a pack of 52 cards?

Answer 1

42, but maybe more.

In the traditional standard English deck design, there are 42 eyes

2 x 2 eyes on each of the 4 queens ==> 16 queen eyes

2 x 2 eyes on 3 kings, but 2 x 1 on the king of diamonds ==> 14 king eyes

2 x 2 eyes on the jacks of diamonds and clubs, but 2 x 1 on the jacks of hearts and spades ==> 12 jack eyes

But continental European decks have different designs for their royalty, which usually show all 4 eyes for each of the face cards, making a total of 48 eyes.
