This is an oddity. A large portrait and not how it looks. It is drawn on ordinary white cartridge paper using a very messy technique I have only used this once. The paper is laid on the floor and compressed charcoal is rubbed and rubbed and rubbed into it. For about 15 minutes, This results in a jet black surface, far blacker than any coloured paper can match. Then you draw on it with white chalk, which gives a pale grey line on the charcoal. Incredibly fragile surface. Just brushing your finger across removes all trace of the white, it is just swallowed by the charcoal. I managed to transport her flat back home and framed her under glass immediately. If I shoved her into teh plan chest along with everything else she would have disappeared the first time I pulled her out.
