For this sign, photo taken in 1975, Michael Summa says it was the "first and only time I ever saw this style sign in button copy" -- and, he's right, the use of button reflectors on warning signs was extremely rare in Missouri. This one was on Ashley Road (US 40, Missouri 5, and Business Loop 70) westbound just outside Boonville.
