32-year-old Dutch illustrator and designer Parra has decorated the Amsterdam underground with his playful, bizarre graphics that span a broad base of themes, from introspective to audacious and bawdy. The mostly self-taught artist seems to channel a vintage form with curves, yet with a decidedly modern, post-pop approach. His vibrant and often humorous images feature a distinctive, hand-drawn feel, and can be seen printed on various exhibitions around the globe—club flyers, record sleeves and billboards—as well as silk screened on tees and sweaters.
