The word Self-control, and Stinky Skunk's photo on the front make this sturdy trading card a quick reminder of the book, Stinky Skunk's Self-Control. The back of the card, featuring the bulleted, 4-part definition of self-control from the book, reinforces the meaning of the word. Children love to collect these 2½" x 3½" cards, and love receiving them as awards for building character.
