Since many of you here are interested in home repair and buildings in
general, I though you may be interested in this place. The front of the
first floor is cast iron.

I went to New Haven today to buy a new Borsolino cap. I'm not sure of the
age of the building, but the business has been here since 1908. The bottom
photo shows the cast iron columns and header trim. Some building used cast
iron for structural support also.
