Brian Heater interviewed Jules Feiffer for his Daily Cross Hatch and has put it up in two parts, the first of which is here. In part 2, Feiffer said, "Though there are still some brilliant political cartoonists. There’s my friend Tony Auth, for The Philadelphia Inquirer and Tom Toles in The Washington Post and Pat Oliphant in syndication. These guys are extraordinary. They’re brilliant."
Feiffer is one of the great political cartoonists of the twentieth century, although most wouldn't categorize him that way.
