Every aspiring comic artist should have this

This is a blog entry with links to the best scans (and history) of Wally
Wood's 22 Panels That Always Work that you are likely to find.
If you have an aspiring comic book artist or writer in your family then
these are a must. Download the images and print them out and stick them
up in the loo or give them to your proto-comic artist with all due
reverence.

Thanks to Neil Gaiman and his blog for this
link.
