Spike Jones is a caricaturist's dream (above)! His head is shaped like an upright football, with a wide, cartoony middle section, and a narrow top and bottom.
The young Liberace had a fascinating face (above)! It was wide with heavily padded cheeks, tiny eyes and a thin, pointed nose and chin. The teeth were tucked way in under the nose, and the hair was combed up and back, making it look like it was on fire.
The older Liberace (above) looks a lot more normal. Plastic surgery?
BTW, this clip is really funny. If you're rushed, then start it at the 2 1/2 minute mark.
Who is this (above)? He has a wonderfully comic face (above) set off by a round, volumetric body and interesting vest wrinkles. Vests were God's gift to caricaturists, but nobody wears them anymore.
This (above) is A. J. Muste, a famous pacifist and thorn in the side of the Johnson Administration. He had a long, narrow head with a huge pointed nose, thick horn rims and a high, bread loaf fedora. This reminds me that most artists don't draw fedoras big enough. A good fedora always changes the head shape, always looks a bit too straight up and awkward.
This (above) is the Mount Everest of eccentric fedoras...true royalty of the hat world. I love the way the hat continues the outline of the hair. If I ever see these on sale I'll hock my children to get the money to buy one.
Stepin Fetchit's half closed eyes (above) and high eyebrows were his trademarks, but the thing that really made them work was the "U" shaped bulge above his nose.
Charles Laughton (above) had even more facial padding than Liberace, but in Laughton's case the pads are relaxed and friendly, and even a little floppy. His face consists of small circles (above) embedded inside larger circles; spheres overlapping spheres.
Last but not least is Louis B. Mayer (above). His head and body look bland and ordinary, but his eyes are 1,000% alert and ready to go on the offensive. It's the contradiction of blandness and unexpected vitality that makes this picture hard to put down.
BTW, I'm in a podcast on the ASIFA Hollywood Animation Archive site!!!!!! This is the second installment, and this came out a lot better than the first. I talk about drawing theories, story, direction, how to do difficult assignments and all that. If you're curious to hear what I have to say, then give a listen!
