Welcome to the Magic Kingdom's magical 50th birthday party and homecoming celebration!
Hint #1
Ok - we'll give you a hint. Your little brother Joe is pointing at your picture! It's part of the steamboat's wheel! Joe is standing just below Mickey/Steamboat Willie's left hand. The dark horizontal line above Joe's head is Mickey's outstretched left arm.
Notice how Steamboat Willie is really composed of faces of Disney castmembers?
