Filmmaker James Gunn has collected on his website a number of anatomical takes of cartoon characters. There are too many to show here, so if you like these go to jamesgunn.com for more.
The fabulous skeletal reconstructions were made by South Korean artist Hyung Koo Lee using resin, paint, and wire. I’ve added the original cartoon images to refresh your memory.
