Just added Rick Stromoski to the author pages. Rick's books were the first ones I did for another cartoonist with the very first epub generating software I used to create an e-book: eCub. Great little free tool but somewhat limited of course. Still it got me a start in the ebook market when just about no one else was talking about self publishing e-books. 
Rick's a funny guy who has been doing cartoons for a long time and making a pretty good living at it. He has the comic strip Soup to Nuts and does a lot of other stuff too that you can read about on the site page and see on his website. 

Besides being an e-book publisher/creator I also do a lot of other cartooning. I belong to the NCS in the Great Lakes chapter and for the last few years we have been placing an ad in the Reubens Journal. The RJ is published and distributed to those attending the Reubens awards weekend held on Memorial Day weekend. I have laid out the ad the last three years and just finished the current one. It's crowded in there! You try herding 19 cartoonists into a small space! Although I am sure it has been done.
