Nicole Hollander, as some of her fans may not know, is an expert in xeroxgraphy.
Because Nicole had to create 6 strips a week (and at some points in her career 7 strips a week), she only drew Sylvia once. She would just xerox off a fresh Sylvia, place her in a new background with a new witty comment, and then send the strips off to her publisher.
I know Nicole will have something to say about me making the creating of Sylvia seem so easy peasy. Bring it, Nicole, bring it. Please tell us how hard your life was doing something you loved. 😉
