My friend Karen and I have been doing a comic book together for 20 years. I write the scripts. She does the pictures. Kinkos does the rest.
You might try publishing those cartoons as posters, or a book and selling same over the internet. Try ads in "Rolling Stone, and a couple of other alternative magazines." You could also send a couple of those cartoons to "Rolling Stone," or "Mother Jones", or "Utne", they might publish them, and that might lead you to a publisher. Any bookstore will have a copy of "Artists' Markets". Check it out. Good Luck.
