Kids grow up
These are the illustrations that go with the sketches below. Why? well, a large theme within the Polar Express (the film and the book) is the loss of faith that creeps in from childhood forward. These paintings are showing that the older boy is slowly losing his belief in Santa, partly due to the 'fake' department store variety and it takes a trip to the North Pole on the Polar Express to restore it (my problem with this, of course, is that Santa is. . .well, you know).
