Scraperboard
I sometimes use
pen and ink for black and white work, but more often than not, I use scraperboard,
because it gives such a graphic image. I use Essdee British board, employing
a number of techniques.
Not many illustrators use scraperboard, certainly very few would bother
to match the detail in, for example, the picture of Marylin.
