Similar drawings appear in many countries. Herbie (Canada), Overby (Los Angeles, late 1960s),[31] Flywheel, Private Snoops, The Jeep, and Clem (Canada) are alternative names.[1][2][32] An advertisement in Billboard in November 1946 for plastic "Kilroys" also used the names Clem, Heffinger, Luke the Spook, Some, and Stinkie.[33] "Luke the Spook" was the name of a B-29 bomber, and its nose-art resembles the doodle and is said to have been created at the Boeing factory in Seattle.[34] In Chile, the graphic is known as a "sapo"[32] (slang for nosy).
