The Queen of Clubs is a very favourable card according to the cards of her entourage; but it is not a good omen having at her side some cards that we will indicate.
The Queen of Clubs represents a brown (brunette), married, well-behaved, very spiritual woman who loves to be of service.
Taken alone by a young girl or a widow, she announces: Rivalry, jealousy.
By a single person or a widower, she represents the woman he will marry or form a long lasting relationship.
For any other person she is a powerful protector and ensures tranquility and happiness.

Diamond ♦: Unresolved disputes over a brunette woman. – Obstacles to your future success.
Club ♣: Certain loss of money. – Still, it is much better to suffer this loss and be rid of a relationship or a casual involvement with a brunette girl rather than continue with it.

EXCEPTIONS.

With the King and the Jack of Hearts: A brunette woman will be flirting, flattering, hoping to take advantage of you. She will use various tricks to deceive your good faith.
With the King of spades – two very bad cards make a very good omen. It means a fundamental change of character – turning from evil to good, finding conscience and generosity in people that are neither trustworthy, nor generous. It also means a happy relationship of two people, who previously were profoundly lonely and unhappy.
