thank you spiderman! Glad you appreciate the pun. It took me a moment to think about it, since I had Max Ernst's title in mind, but knew it was his, so ..... once I've done the opposite, a title for a painting was "Ernsthaftes Spiel im Inneren Erdteil" - since it was done in decalcomania technique, like Max Ernst also used. It translates into "Serious (or Earnest) Play in the Inner Continent". That one I sold to the director of the Ernst Fuchs Museum in Vienna. I posted this 6 months ago: https://steemit.com/art/@thermoplastic/ernsthaftes-spiel-im-inneren-erdteil.
Re tip about the eraser: it takes a bit of practice, but it's great for cutting corners. You have to find out what works and what doesn't. Mentioned Fuchs above: I am at his museum frequently, and am studying his graphic work, and while I came upon my methods by myself, I noticed that he was using some similar shortcuts also.
