About 30 kids showed up for Nora Litz’s workshop in Philadelphia called “Illustrated Migration Stories.” The assignment, completed over seven recent Saturdays, was to tell their family’s story — how did they get here, to the United States? — and to illustrate it. The children were all of Mexican decent.

Litz, an artist, writer and activist from Mexico City, wanted to help the kids articulate their feelings and deal with the fear and anxiety they’ve felt since the U.S. presidential campaign and election. The kids, ages seven to 15, are all too aware of the immigration controversy swirling around the adult world above them, and of President Trump’s hard-line stance. And while some kids did illustrate their journey from Mexico to the U.S., many others told the story of what’s happening in their homes right now.

“A lot of it was the drama of being told by their parents, ‘If someone comes to the door, don’t answer it,’ or about the preparations being made. ‘If we don’t come home, who do you call?’” said Tim Whitaker, founder of Mighty Writers, the nonprofit organization that offered the program. Mighty Writers’ goal is to help kids learn how to think and write clearly.

These comics — funny, sad, startling — are a window into the world of a group that has no voice in the immigration debate but are already heavily affected by it, and has a lot to say.
