The printmaking professor at La Sierra University in Riverside, CA, invited Christian Ward and I to come out and do a demo on collagraphs with monotypes, and to do a brief Powerpoint presentation on our own work to a combined group of classes.
Here's a portrait of the student Kiyomi, who I've hung out with before. It's done with Akua ink and monotype, then I printed the ghost with a collagraph plate.
