This type of vernacular architecture in which buildings are designed to imitate the products they sell was a trend in California decades ago, and perhaps that was the inspiration for this building. Are any readers familiar with the Randy's Donut Shop near Los Angeles International Airport? There are other buildings in L.A. in which camera shops were shaped like a camera, hot dog stands shaped like a hot dog, and similar "kitsch."
I wonder how the architect told the builder to construct this wave. It looks rather tricky.
