So so so many, and across such a broad spectrum. You didn't even mention Asterisk (Albert Udurzo), which looks so gorgeous it genuinely put me off superhero comics, which looked crude by comparison. My absolute political cartooning hero is Sir David Low. His "jokes" were just timeless, and his line work and composition is superb. There are also the classic Punch magazine artists like Pont.. Then you have Ralph Steadman, and Gerald Scarfe. For current stuff, Ann Telnaes is just impeccable. I don't think you event mentioned Chuck Jones, perhaps forgivable, but not to mention Maurice Noble's backgounds!

One confusing thing here.. at least from what I can find on sale in the UK at the moment... Conte Pierre Noire 1710 isn't actually charcoal, it's pastel (the fusian 720 appears to be their chacoal range). Even more confusingly though, the fusian is the one with the gold ring around the end (pierre noire doesn't have one, at least not the b or 2b). It might well have charcoal in it, it's just not what they sell as their charcoal pencils, and feels very different to other charcoal pencils I've used. Not that any of it matters that much, I've bought a bunch of both, and the 1710 really is a lovely pencil (definitely acts more like pastel than charcoal.
