I have drawn thousands of single-panel comics over the last 11 years. They are mostly on evaluation related topics, but I also touch on topics related to research, data visualization, entrepreneurship, and design).

Just about every blog post I share on freshspectrum includes at least one cartoon. Some include lots. Outside of this blog, you’ll also find my cartoons in other people’s presentations, books, blog posts, and on office walls worldwide.

About those cartoons, umm, can I use one in a…

So I creative commons license all of my cartoons. So yes, you can use them.

How do I attribute?

Technically I only require that you keep the “freshspectrum” signature on the cartoon. But I do appreciate links back to my website. So my preferred attribution would be something like this…

“Comic by Chris Lysy of freshspectrum.com

And if you do use that line, please also link to my main website.

This site is called Evaluation Comics, but the cartoons are signed freshspectrum, what’s the deal?

This Evaluation Comics site is a freshspectrum spinoff. For over a decade I signed my cartoons as freshspectrum hoping to inspire people to visit my blog. And now that freshspectrum information design is my business, not just my blog, why stop now?

There will always be a comics link on freshspectrum that bring visitors to this site.

But what if it’s commercial?

Ask me (send an email to chris @ freshspectrum .com) most of the time I’ll just say go for it.

Where do I read your cartoons?

Here on this site! I post new cartoons on Mondays, Wednesdays, and Thursdays. You’ll also find cartoons on my blog > freshspectrum. You can also follow the cartoons by email. You’ll get a single email every day that I post a cartoon (so three a week).

Do you have a book?

I have one cartoon book (Evaluation Illustrated), it’s filled with over a hundred audience favorites. You’ll find it on Amazon and some other booksellers.
