Waldo is a fictional character created by American author and illustrator Martin Handford. He is the protagonist of the WHERE's Waldo? series of children's books, which feature him in detailed, crowded drawings of people and places. The goal of the books is to find Waldo, who is usually dressed in red and white stripes, among the other characters in the drawing. The term 'WHERE's Waldo?' has become a popular phrase used to describe a situation WHERE someone or something is difficult to find.
