I am neither an artist nor am I a cartoonist but I can recognize the art in a good cartoon that is both thoughtful and thought provoking. . . Every once in a long while I post a cartoon here. In particular, I commend Dave Walker at CartoonChurch.com who is very kind in making such occasional use of his work both easy and free. If you are looking for a good source of supply, check him out. You may not always agree with or like his cartoon or his humor or his point but it is always well crafted. He is reasonable for those who are looking for more regular use ($55 per year is a general license).
