Altus Inc , an Engineering and Technical Services firm, highlights history in their Darlington office location. Old photographs acquired from Harford County Historical Society grace the walls in several rooms of this office. Featured in the main hall is a trio of photos dated back to the early 1900s of the old post office, town garage and ministry meeting house. A classic antique style ornate black frame is used to compliment the time period. A triple mat design with spacing in between a layer draws you to the photograph. Two other rooms in the Altus building feature framed historical Darlington art.
