In the very early 1970s I created a series of small scraper board images, using a set I purloined from my mother. Black Indian ink laid over a white waxy base. You scraped through with a little knife to create a white image. I loved the effect and it was easy to correct with black ink. The viking ship was the first one I did. All the rest are vaguely Tolkienesque, apart from the Blake poem, which was on white scraper board.
My sister has one other that I did, of a king either gazing into a crystal ball, or just about to bowl for a strike. It’s all a matter of viewpoint.
