Here are some more pictures of the engraving process, and the second proof as work continues on a small copper plate of Walking Man observing and drawing a comet.

would it be possible to use the second image ‘Detail of a small curl of copper being plowed up by the burin’ on an open access educational website to illustrate the historic way that copper was worked with a burin to produce early maps? Do you have a higher res image?
Yes, i would welcome that too! I would like to use the same image for explaining the technique to a non-commercial group of Dutch technique lovers.
You are more than welcome to use the image
You are very hospitable. Thank you very much!!
You are welcome!
