Plumbago drawings are graphite drawings from the 17th and 18th centuries. There was a group of artists whose work in plumbago is remarkable for their portraits drawn with finely pointed pieces of graphite and on vellum. These works were initially prepared as the basis of an engraving. Eventually they would be produced as works in their own right.
