Reddit reviews Anarchy Comics: The Complete Collection

You can start with a little levity.

Anarchy Comics: The Complete Collection edited by Jay Kinney covers much of anarchist history in comic book form.

Or you can have them read Orwell on Anarchism and see if it gets them curious.

A Chapo Guide to Revolution and Anarchy Comics: The Complete Edition are good places to start. I've also seen people recommend The ABCs of Socialism, but I haven't read it so I can only say I've seen others say it's good.
