Richard, in addition to the usual Cul de Sac strip in the Post's Magazine, has a piece on how to create a cartoon in the Style & Arts section. Giving away part of it, a hammer, a head and drumming might be involved. Richard's posted it on his blog too.
AND, he has a full-page illo for an Achenbach article about open houses later in the Magazine as well.
Chilling, isn't it?
