I came across these images while searching for “Clipper” sketchbooks, after finding out that Richard Diebenkorn used them. The Clipper Sketchbooks below are from the website of Albert “Abby” Sangiamo, an artist who taught at the Maryland Institute College of Art for 50 years. He unfortunately died a few months ago.

You can see all the interior pages of the various sketchbooks here: Sketchbooks | Abby Sangiamo – Drawings & Paintings
