Lion
Picture book · ages 4–8 · 380L · 1983
A quiet, genuinely kind story about a lion who disrupts expectations—du Bois's illustrations are restrained and elegant, and the pacing is patient enough to let five-year-olds sit with the feeling.

The Twenty-One Balloons
Middle grade · ages 8–12 · 750L · 1999
A Newbery winner that earns it — ingenious premise, beautiful technical illustrations, and a protagonist who thinks his way out of catastrophe rather than stumbling through.

Bear Party
Picture book · ages 4–8 · 250L · 1975
A gentle, nearly wordless party romp with du Bois's clean Mid-Century Modernist illustrations—sweet and easy, but thin on plot or character growth.
