The vividly colored Gasoline Alley used to fill an entire page in the Sunday newspaper comics section. In this early example, Uncle Walt and little Skeezix enjoy an outing in Walt’s roadster until the radiator boils over, which cuts short their trip. Frank King debuted Gasoline Alley in 1919. When Baby Skeezix appeared on Walt’s doorstep on February 14, 1921, the characters began to age normally, a ground-breaking development in comics. The strip continues to be published.
