This is an usual modern example of a painted building logo, this one located on the roof of the Bubba Gump Shrimp Company restaurant in Denver, Colorado. Bubba Gump's is a chain, but I doubt all have this feature. This painted logo, viewed here upside down as viewed from the Embassy Suites, is painted so that the logo is visible from the hotel across the street.
This was photographed on a snowy day, so the logo is not entirely clear.
