and in 1916, a son, Robert Drew King, was born. It was at this time that the family moved to 533 Madison in Glencoe, a somewhat affluent suburb on Lake Michigan north of Chicago. In 1916, King's salary from the Tribune was $5000. By 1925, this had grown to $22,500, a princely sum that was augmented by royalties from Gasoline Alley books and toys. The Rectangle The Rectangle began as a Chicago Tribune page featuring a variety of cartoons and serial features. King's Rectangle Sunday page, usually printed in black-and-white outside the comics section, was a late addition to a page that ran for years in the Tribune. On January 9, 1913, King introduced a bounded rectangle containing themed single-panel gags (beginning with a page headed Hints to Husbandettes), but pages in that format did not appear with any regularity until February 1914. The Rectangle title was finally introduced on December 27, 1914. King created several recurring strips, including Tough Teddy, The Boy Animal Trainer, Here Comes Motorcycle Mike, Hi Hopper (about a frog) and his first successful full-page comic, Bobby Make-Believe (January 31, 1915 to December 7, 1919).

Bobby Make-Believe, Here Comes Motorcycle Mike, Hi Hopper and other pre-Gasoline Alley comic strips by King were reprinted by Sunday Press Books in a hardcover titled: Crazy Quilt by Frank King: Scraps and Panels on the way to Gasoline Alley, Comics from 1909-1919, (2017), ISBN Gasoline Alley On Sunday, November 24, 1918, the bottom quadrant of The Rectangle featured Walter Weatherby Wallet and his neighbors Bill, Doc and Avery as they repaired their automobiles in the alley behind their houses.

I'd go to his house on Sunday, and we'd go down the alley and run into somebody else and talk cars. That was the beginning of Gasoline Alley." After King began the daily Gasoline Alley strip (August 24, 1919), The Rectangle appeared sporadically and finally came to an end on February 8, 1920. King often credited his wife, Delia, for providing a "woman's angle" to Gasoline Alley. The central character of Walt was based on King's brother-in-law, Walter White Drew
