Looking around the corner of a building can reveal a lot. For this Pullman row house, it makes visible the contrast between the common brick (locally sourced and used for construction) and the facing brick (brought in from an out-of-state brick factory where consistency, size, and smoothness are better controlled). The more expensive houses have the nicest materials and decorative pieces, while the least expensive row houses in Pullman are entirely of common brick. Of course, we still do this kind of thing today. Is the front of your house nicer than the back?
