If someone could shut up those guys on the corner two blocks from your office—the ones who never give it a rest with the come-ons—that person would pretty much be your hero, right? Your superhero, actually.

Done. Meet your superheroines: from left to right, Philadelphia artist Erin Filson, and Anna Kegler and Rochelle Keyhan of Hollaback Philly, an outpost of the worldwide organization working to end street harassment.

Their weapon of choice? A comic book. Hollaback: Red, Yellow, Blue follows two women enduring street harassment (Red and Yellow) and a male bystander to the act (Blue). Sharply drawn and boldly colored, the illustrations are so cool you want to frame them—but the book is 100 percent aimed at educating. (Even more impressive—the e-book will have an interactive, choose-your-own adventure element.) I talked with Rochelle, Anna, and Erin about their own harassment stories and Hollaback's quest.

Why address this issue through a comic book?

Anna: Storytelling is a big part of trying to fix street harassment.

Rochelle: It's so important because the mainstream narrative is not by women. It's definitely not by women of color, and then you factor in LGBT [issues]...storytelling is a way to add our reality to the main narrative. And it's therapeutic for the people telling those stories, people who have experienced street harassment and heard, "Oh, you're overreacting. That's just boys being boys." Or "You can't take a compliment."
