Unlike in most comic strips, the time in Gasoline Alley passes at a reasonable pace and the characters grow old and eventually die. In its early run the main protagonist was a mechanic named Walt Wallet and most strips consisted of him and his friends Doc, Avery and Bill talking about automobiles. In 1921 Walt adopted a doorstep baby nicknamed "Skeezix", who eventually grew to replace Walt as the main character of the strip.
Season 1 Edit
Jimmy anachronistically references the strip while having breakfast with Angela, Tommy and the cat in January 16, 1920, calling Tommy "Skeezix" a year and a month before the character was first introduced. ("Boardwalk Empire")
