In his essay for Leonard Edmondson: Art of Discovery, David Acton wrote the following about the mixed technique color intaglio Exodus: “Edmondson’s friend, the ceramist Peter Voulkos also influenced his work in the late 1950s….Edmondson’s print Exodus is not unlike Voulkos’s sculpture in its rugged, agglomerative composition. He pressed plastic shapes side by side, balancing them with voids of white paper to draw the viewer around and through the composition. He etched the printing plate in stages, allowing the acid to bite some passages deeply, and pressed the sheet into textured surfaces. A sense of expressive energy in this print and its seeming spontaneity of design are also unusual for Edmondson.”
