The artists repository and drawing magazine: exhibiting the principles of the polite arts in their various branches
A late eighteenth-century English drawing manual of 1787, compiled to teach the polite arts and held by Heidelberg University Library, aimed at students and amateur draughtsmen. The pictures are sepia-red chalk-manner studies of heads in profile and three-quarter view, showing old men with beards and caps alongside a young woman in a bonnet, all in soft stippled tone that a designer could use for character portraits or hatched tonal portrait references.
