While photographing the Art Deco Lamb house in Ogden, Utah, I realized I had seen it before, in an ad for Insulux glass block. I had the certainty of an eyewitness, and now I see why eyewitnesses are often unreliable.
I was right about the Insulux. But the house I had seen was the L.M. Persons house in St. Louis. Does anyone know if the L.M. Persons house still exists?
