An illustration is a visualization such as a drawing, painting, photograph or other work of art that stresses subject more than form. The aim of an illustration is to elucidate or decorate textual information (such as a story, poem or newspaper article) by providing a visual representation.
Scratchboard is a technique where drawings are created using sharp knives and tools for etching into a thin layer of white paper or clay coated with black India ink.
