The Duquesne Club around the corner may be the center of power in Pittsburgh, but this more modest club also possesses some influence. The Alcoa Building (a bit of it is visible in the left background) actually has a notch cut out of it to avoid demolishing any of the club. The club seems to have been made from late-nineteenth-century rowhouses (back when there were still such things downtown), remodeled into a luxurious club in the 1930s.
