I recently made a sticker comic with Digitalcourage (npub1t3g…qqds) but it’s in German.

There‘s also a half finished talk for Project Rosenpass (npub1vje…q05t) comparing communities on the internet to pacific islands.
And a few projects with Free Software Foundation Europe (npub16xn…g7f8) like the mini comic for I love free software day.
They also have a great children’s book that might be closer to what you’re looking for:

My own comic still needs time.
