Here’s a great little antique cartooning tutorial by Bill Nolan, “Cartooning Self-Taught” they posted recently on the excellent ASIFA-Hollywood Animation Archive Project Blog.
Along these lines I recently noticed that Dover, excellent inexpensive publisher of wonderful reprint books and clip art books, has reprinted some old cartooning books, including one by the wonderful George Carlson, who wrote and illustrated one of the greatest comic series of the golden age, Jingle Jangle Tales. All of these books are extremely cheap, and look quite cool… I haven’t got them yet, but I plan to.
