Here are some additional details about Arthur's appearance from the book:
* "He was tall and thin, with blond hair that hung in his eyes." (Chapter 1)
* "Arthur Bauer was a skinny, pale boy with eyes the color of a summer sky." (Chapter 8)
* "Arthur Bauer was a long, thin boy who always wore a white T-shirt and jeans." (Chapter 12)
Arthur's appearance is often contrasted with Erik Fisher, who is described as a stocky, muscular boy with dark hair and brown eyes. This physical difference is symbolic of their contrasting personalities and values.
It's important to remember that these descriptions are based on the novel and might not be a perfect representation of how Arthur would look in real life. However, they give us a good idea of his general physical characteristics.
