Amid the trash-filled streets, bleak concrete-block storefronts, and grimy open-air workshops, Pakistan's decorated trucks stand out in their colorful and vibrantly ornate aesthetics. A typical truck might be festooned with dozens of stamped metal plates, lavishly painted panels detailing birds, saints, and landscapes, a high wooden prow of carved wood, and a long skirt of hundreds of chains with bells on their ends, which give the vehicles their common English moniker, "jingle trucks."
