“One ‘Gasoline Alley’ Sunday page from 1930 offers a typically bittersweet moment. As father and son take a walk in the fall, Skeezix asks Uncle Walt why the leaves change color. (King was the first cartoonist to forgo the convention of comic strip time and let his characters age.) The answers that Walt provides are less important than the tone and texture of the scene, a leisurely communion between parent and child marked by an undercurrent of sadness, the feeling that even when the idealized world of comics brings fathers and sons together, they will not be together forever.”
