Henry Rollins, in his journal collection "Get in the Van", notes that Pettibon's artwork became synonymous with Black Flag and that before Rollins joined the band he would collect photocopies of their flyers that had circulated from California to Washington, D.C. The album cover for "Nervous Breakdown" had a particularly strong impact on Rollins: "The record's cover art said it all. A man with his back to the wall baring his fists. In front of him another man fending him off with a chair. I felt like the guy with his fists up every day of my life." Another image which drew considerable attention was the artwork created for the "Police Story" single, showing a police officer being held with a gun in his mouth with the speech blurb "Make me come, faggot!" The image was plastered on flyers all around Los Angeles and added to the police pressure on the band. Pettibon later remarked that "my values are relativistic, and I'll give a cop the benefit of the doubt. If that's me with my gat – my gat's larger than the one depicted – we can have a discussion, and he can answer me just as well with my .357 barrel in his mouth, or on his cheek, or on his adenoids, or down his throat. I'll listen to his whimpering cries."
