Deep in the huge stockroom of Bronner’s Christmas Wonderland, a holiday supercenter about 80 miles north of Detroit, a man named Jason was assembling a 17-foot Santa. Each body part, painted bright red and black, hung from a hook in the ceiling like a cow carcass in a meat locker.

Wayne Bronner, 67, the chief executive of Bronner’s and one of nine family members associated with the company, stood next to the smiling, rosy-cheeked head — it was almost as tall as him — to explain that this model would be marketed through the commercial sales department.

So somebody was going to buy this 17-foot Santa?

“Oh, yes, definitely,” he said.

That Santa is just one example of the Christmas bounty available at Bronner’s. A major node of what might be called the Christmas industrial complex, the store, in Frankenmuth, Mich., ships merchandise to every continent. It provides countless props to Hollywood. And it is open 361 days a year.
