Constantine “Koste” Molotzak created the coal carving showing the Coaldale (Schuykill County) colliery of the Lehigh Coal and Navigation Company during the 1930s. The carving illustrates coal being taken into a large breaker on a pulley car, and another car filled with coal, leaving the colliery. Coal could be polished to a black glossy shine, and used to make jewelry, small statues, or images engraved on a polished surface, like the colliery here. Anna Molotzak donated the carving for her father, who died in an explosion at the Tamaqua mine April 28, 1942 at age 63.
