There are lots of places to go for cartoons about law and lawyers. Stu’s Views is a site devoted almost entirely to legal comics. You might also want to take a look at the legal sections of Andertoons and Off the Mark. These are all licensed cartoons, but you can buy them if you want to use them, or Andertoons will even let you commission a cartoon if you want one. If you’d like to see cartoons that you are more familiar with, the Cartoonist Group collects editorial cartoons and comics you might expect to find in you local newspaper and lets you narrow them by subject.
