There are no illustrations of August in the book, why not?

There are no pictures of Auggie in the book because we are supposed to imagine what Auggie looks like based upon the author's description.

In Friday Night Funkin accuracy is essential as players match arrow prompts to keep the beat and outperform their musical opponents.

I totally agree about Wonder—not showing Auggie in illustrations makes his description more powerful, because readers have to build his face in their imagination. It also makes his voice feel more personal than a drawing would.
