Drawing, as the origin of all graphic arts, is one of the oldest cultural techniques of humanity. The drawing, which can be implemented with simple technical means, is still the medium that gives the most direct expression to the ideas of artists. As a sketch, a study or preliminary drawing, it helps both in the transformation of what has been seen into an aesthetic form, as well as in the development of ambitious compositions. Etching and other graphic reproduction techniques developed over the centuries, and were initially intended to reproduce the ideas held in a drawing in order to share them with fellow artists and an ever-growing circle of interested people.
