It had two and a half pages of ads (including Kirby's first published full-pager) for the Lone Rider feature that would begin in the next issue. This made Kirby's page count for his first year in the industry twenty-four and a half pages.
About a year and a half earlier Kirby had been hired by Associated Features Syndicate to produce his first daily strip. It was a knockoff of the Lone Ranger, a character that had at that point been on the radio for four years and star of his own monthly pulp magazine for half a year. The Lone Ranger comic strip appeared in newspapers from September 1938 to December 1971. Kirby's Lone Rider strip appeared from January 1939 until February 1939. Thirty-two of those strips were colored and a reprinted four to a page, two pages an issue in FAMOUS FUNNIES #62, 63, 64 and 65.
There are four Lone Rider pages restored by Joe Simon biographer Harry Mendryk on exhibit at http://kirbymuseum.org/blogs/simonandkirby/archives/591
