Studienblatt_ Maßwerkfenster in Eberbach und Hirschhorn 

This pencil drawing by Karl Ballenberger, a 19th-century German artist, depicts five different architectural designs for Gothic tracery windows. The detail and precision of the lines suggest that this was a study for a larger project, perhaps a building renovation or new construction. The labels "Eberbach" and "Hirschhorn" indicate the specific locations of the windows that inspired these designs. These drawings offer a fascinating glimpse into the meticulous planning and artistic sensibility of architectural design in the 19th century.
