When Stanley Lambchop wakes up one morning, his brother, Arthur, is yelling. A bulletin board fell on Stanley during the night, and now he is only half an inch thick! Amazing things begin happening to him. Stanley gets rolled up, mailed, and flown like a kite. He even gets to help catch two dangerous art thieves. He may be flat, but he's a hero. This is the very first Flat Stanley adventure, updated with crisp new art.

Flat Stanley Stanley Lambchop wakes up one morning to find a notice-board has dropped on him in the night, leaving him happy and healthy, but only half an inch thick. It's a little unusual, but he finds he can fly like a kite, be sent on holiday through the post and can use his special new skills to catch some art thieves. Still, he's glad when his brother Arthur thinks to use the bicycle pump to inflate him back to his normal shape.
