Pen & Pixel is a Houston, Texas-based graphics design firm that specializes in musical album covers, especially for gangsta hip hop artists in the Southern US. For a long time it was the house design firm for the famous No Limit Records label.Pen & Pixel is famous for its identifiable design vernacular of gaudy 3D- and effects-laden text like album titles and rapper stage names which are often “studded” with diamonds or made to look like marble through heavily layered PhotoShop-filtered graphics. These typically overlay a scene depicting the album artist ostentatiously surrounded by women, liquor, gold- and diamond-coated material effects, and other signifiers of a gangster lifestyle.
The company’s CD cover art usually includes paraphernalia associated with wealth like luxury cars, helicopters, candlesticks, dollar bills, and women. Such displays often contrast said wealth against the woes of poverty amin New Orleans and the American south. Beyond materialism, common themes discussed in the company’s oeuvre include: death, violence, criminal guilt, manhood, persecution (especially by police), and urban paranoia.
