A NOTE FROM THE ARTIST ABOUT MATERIALS AND TECHNIQUE: "I create hidden image pen and ink art. Each drawing contains dozens of hidden animals, people, or objects. Most drawings come with a separate answer key showing what's in the drawing. The drawings are done on acid-free Bristol board with rapidograph pens with points as small as .13mm. For example, my "Tiger" drawing is comprised of 171 hidden animals. My motto is "Look Closer!""
