Here's a photo of Chuck Jones's hands with a Blackwing 602.
Artists' hands are a tool as much as the pencil, brush, or mouse are and they reveal much about the artist's personality and character just in the way they hold their instrument, or touch the paper, even in a still image such as this one of Chuck Jones at his drawing table in his home studio.
When you see Chuck Jones' hands, the left holding the paper in place, the right with his favored pencil (the Eberhard Faber Blackwing 602, no longer in production) it's easy to imagine that you hear the gentle scratch of lead on paper, and witness the brisk, sure movement of his hand delineating the character of Elmer Fudd and Bugs Bunny as surely as someone who completely understands their motivations, personality tics and eccentricities as he does his own.
“…unlike so many animated characters, Daffy doesn’t wear gloves. His hands have a thumb like a human thumb and pointy fingers that are a cross between human fingers and a bunch of feathers.” –Chuck Jones writing in Chuck Reducks, Drawing on the Fun Side of Life
