This was evidently the first year of what would become Frank's annual temperance picnic. The picnics continued up through his death in 1937, featuring well known speakers. For example, in 1932 future governor Alf Landon participated. Kansans voted the following year to prohibit the sale and production of alcoholic beverages. Later in his life, as detailed in his autobiography, he became a genuine crusader against alcohol.
These are two pages from the 1909 picnic program.
