I enjoyed learning about various printing technologies, seeing the railroad artwork, and learning about some unpleasant aspects of life in a different time. Thanks for sharing it.

P.S. While Broad Street Station in Philadelphia is long gone, nearby underground Suburban Station is still a busy commuter hub. City Hall (standing behind it) still stands as the municipal center of the city. The tower, with its statue of William Penn, remains a city landmark. The city’s two subway lines (Broad Street and Market-Frankford) meet underneath it. For many years, tradition had it that City Hall was to be the tallest building in the city, but eventually other buildings exceeded it.
