Today's Archive Dive is from September 1, 2009, when I pointed out this fantastic guide to cartooning from a prominent Disney artist.
Carson Van Osten, a famous Disney artist who did many Disney comic books, created the famous "Comic Strip Artist's Kit." It was designed to help beginning comic artists deal with perspective problems and other drawing difficulties. They're still as rock solid today as they were when he created them in 1975. Enjoy.
