Roy Crane was an influential comic strip artist that pioneered the adventure strip format. James Gurney, on his blog, recently linked to some pages of a "scrapbook" Crane put together to help other artists assist him in drawing his comic.
It's a great handout, covering such topics as composing for a comic strip, using black, white and grey, and how to draw women. Much as I've tried, I can't find the whole thing in one place. But here are links to some pieces I've found:
From the blog Hairy Green Eyeball 3 - Roy Crane's Art Technique and his Lost World!
From the blog Mike Lynch Cartoons:
Roy Crane and Buz Sawyer
Roy Crane: How to Draw Buz Sawyer
1970: More of Roy Crane's Scrapbook
Roy Crane Scrapbook: How to Draw Women
If anyone knows where to find them all in one place, or knows where there are more of these pages, definitely let me know! This stuff is great and thanks so much to the blogs that have posted this stuff. It's amazing!
