A very simple, less than 5 minutes, nude study drawing in hard pastel from a sketch pad that I used when I was teaching life drawing. It must have been done as a demo for someone.
Please note that this drawing is on ordinary pastel paper (the sort readily available to non-professional artists) and the paper is not archival quality. Consequently there will over time be some discolouration to the paper, the lights used to photograph the drawing have picked upand emphasized the start of this process. Foxing etc is always going to happen over time with the usual wood pulp papers that are available in art shops. Its effect can be minimised by avoiding wood based materials coming into contact with the paper, eg. using an acid free board in the back of the frame.
