These cartoons can be used by organizations that work to protect wildlife and the environment. Email a request to deannorman01@gmail.com. and I can send you a pdf file of 50 cartoons to look at. If you see a cartoon you can use, I can send a digital file at 600 dpi (black and white version), or at 300 dpi (color version). The cartoons in the pdf file are 96 dpi which would work on a website, but not good for print publishing. I am preparing additional volumes of nature cartoons. There will be about 900 total. Some of them have been published in magazines and newspapers, and all of them are in book collections that are in the archives of The Billy Ireland Cartoon Museum in Columbus, Ohio.
