This card is the second most popular card in a standard deck of playing cards, next only to the Ace of Spades.
Ask any magician out there who has worked for a long time. When asked to think of a card without any restrictions, the most common card people think of would be the Ace of Spades. When women are asked, a significant number of them think about the Queen Of Hearts.
The first thing most card readers learn when learning how to predict the future by using cards is how to seek out four cards in the deck: the Ace of Hearts, the Ace of Spades, the King of Spades, and the Queen of Hearts. For some reason, out of all the face cards, the Queen of Hearts really commands the most recognition. She supposedly represents Judith from an apocryphal book of the Bible.
The fact remains that one of the most potent weapons in a magician’s arsenal is a deck of cards, and the Queen of Hearts appears to be a favourite card for magicians who want to hint at anything romantic with the girl. Why go for a five of diamonds when you can go for something latently symbolic like the Queen of Hearts?
Anyways, I digress. Out of the many symbols of love available in the lore of magic, I suppose this card in particular is one of the most recognizable ones out there.
