Philadelphia Waterworks print"The Dam And Water Works Philadelphia"  is one of two patterns on a 10 inch plate depicting this view.  However, each view has a different boat in the foreground.  This pattern is known as "Stern Wheel" boat view, as opposed to the "Side Wheel" version.  The backgrounds of the Water Works are the same on each.  The source of this view is a drawing by Thomas Birch, engraved by R. Campbell, 1824.  The pattern was made by Henshall & Co. (1790-1828).
