A search of the archives of Arizona's Highways magazine found that Bil Keane's cartoons or articles about Keane appear in more than a dozen issues of Arizona's Highways between 1966 and 1989, but it appears that after 1989 Bil was no longer featured as extensively, perhaps due to advancing age (speculation).
Bil Keane (William Aloysius Keane) (1922 - 2011)
Bil is well known for his Family Circus "dotted-line" maps
