Some readers were curious about the etching I used to make the rubbing yesterday. Here is the deeply etched copperplate, about 12.5 x 28 cm. You may have seen it before though I could not find more than a small section of it. The etching was originally created for the Meta-morphosis VII group of prints and used again in Nexus Blue IV.
Still inspired to play some more with rubbings and drawings, I did several more today with this copperplate, above and below are the best two. I think I like yesterday's better - beginner's luck!
