Harry Potter and the Philosopher's Stone/Harry Potter and the Sorcerer's Stone - Quidditch Scarf
On the cover of the book Harry is standing on platform nine and three quarters, wearing his quidditch scarf, looking amazed at the Hogwarts Express and experience of the magic entrance.
Harry didn't know what house he was in until he got to Hogwarts so he couldn't be wearing his scarf BEFORE he got on the train!
