KARACHI: With their gleaming steel bodies, hand-painted motifs, colored bulbs and thumping Japanese woofers, Karachi’s W-11 minibuses were once the most flamboyant vehicles on the road: moving art galleries that defined the city’s visual identity and became a symbol of its chaotic charm. For decades, the wildly decorated buses ferried thousands across Pakistan’s largest metropolis, earning global attention through documentaries, exhibitions and even a temporary London art route themed around W-11 culture.
