We've used Mark's cartoons for several years in the e-newsletters that we produce for computer resellers across the country. I am always able to choose a cartoon that is a perfect fit for us. His work is timely - and always funny.

My science cartoons are fun to use in newsletters, presentations, advertising, magazines, books and textbooks, greeting cards, training manuals, and anything else that could use a good laugh!
