Abstract
In 1996, Argumentation and Advocacy published a groundbreaking issue devoted to visual argument. It was the first collection of essays on the subject. Twenty years later, we consider some of the doubts about the possibility of visual argument that were discussed in that first issue. We argue that these doubts have been answered by the last 20 years of research on visual argument, and we look at some of the key theoretical and applied issues that characterize this burgeoning subfield in the study of argument.
