Outside of Sparta, Wisconsin, is FAST Corporation, another manufacturer of giant fiberglass figures, who have been doing this work since the early 70’s. They are the ones who constructed the giant Muskie fish building, that is home of the Freshwater Fishing Hall of Fame.
I was driving by FAST Corporation around 2000, shortly after a powerful storm had blown over some of the fiberglass statues. I took a few photos, and later sent them to cartoonist Bill Griffith, who based a series of ‘Zippy the Pinhead’ strips around those photos. Here is one of them.

It provides great comfort when one browses the on-line catalog of FAST, knowing that most of these are scattered all over the U.S.
