Jacob Sweitzer was an artist from the Armagh area who lived from 1848 to 1947. Sweitzer's primitive artwork features many scenes of the area around Armagh and the Conemaugh River. He often painted on the backs of Shredded Wheat boxes and used local plants and berries to make his own paint.
The above photo is reportedly a painting of the Buena Vista Furnace. We write reportedly Buena Vista because there are several features of the painting that do not match the appearance of Buena Vista: the arch on the front of the furnace is shaped differently and the color of the Buena Vista Furnace is a grey limestone, not the brown sandstone color as depicted.
The photo of the painting was taken by Bruce Siskawicz of the Tribune Review. The furnace is located along the present-day Ghost Town Trail.
