 From March to September 1916, it appeared as "The Escapades of Mr. Jack".Returning to the "Mr. Jack" title, the strip continued until at least 1919.The latter date is given in some sources for Swinnerton's work, though Markstein notes that some later strips depicting Jack surreptitiously drinking alcohol behind the backs of police officers appear to date them to the Prohibition era of the 1920s.
