The Trib article indicated that staff members did not know where the sign originally came from. Allow me to help "fill in" that blank. The sign was ordered by Otto VandenBosh, owner of Miller Chevrolet, from Challenge Stamping and Porcelain Co. on Jackson Street in Grand Haven.
At that time, Challenge manufactured thousands of porcelain signs and curtainwall building panels commonly used throughout America's commercial architecture. Floto's turquoise panels downtown are vintage Challenge; the large Dake letters; the curtainwall building panels framing the roof line of White Pines Middle School; the red storefront of the Grand Theatre are all examples of Challenge's work, manufactured locally by the 275 employees during CS&P's heyday in the 1960s.
Thank you, Gage, for saving and now enhancing this piece of local history!
