Monsieur Madame (Mr. Men in original version) is originally a series of children's books written and drawn by Roger Hargreaves (1935-1988).
Each book depicts the humorous adventures of a character each time different, identified by a particular characteristic (Monsieur Parfait, Madame Princesse, Monsieur Costaud ...) and drawn in a very simple and vividly colored style.
This series of books quickly became fashionable and adults, each finding a trait of their personality, quickly got involved ...
Monsieur Madame has therefore become a fully-fledged brand of clothing and accessories known worldwide.
