Comic artist Will Eisner, who died last week, was more than a pioneer of an underappreciated art form. He was, in his own words a “social reporter”, a politically engaged artist who made a point of digging out a side of modern reality that would otherwise have been hidden from much of the world. Furthermore, Eisner was notable for the longevity of his creative impulse – the work he created in his 80s was as dynamic and rebellious as the graphic novels that first made him famous.
