Deborah Spanton is proof that being an artist is not a retiring-at-65 type of job. The Portland, Oregon, printmaker is in her 70s and still experimenting with media and style. Her influences are varied, including such artists as Wayne Thiebaud, David Hockney and Louise Bourgeois. Spanton’s main theme now is “reflecting upon the strange and unsettling mood in which those of us who call the United States home find ourselves living.”
