Walking down the sidewalk across the street from the Dollar Bank main branch in Pittsburgh, there is an interesting double door. I don’t know what the doors lead to, as whatever used to be in that part of the building appears to have been closed for years. There are no signs for a business, club or office. It just is a door. But what a door. The double doors are made of metal (brass?), and each door has five of these “flower” panels.
