This photo taken on April 7, 2018, shows Indian artist Kalpana Singh painting Mithila or Madhubani paintings on a silk cloth in Madhubani in Bihar state. Under Indian Railways "Rail Swacch Mission" cleanliness drive, worked relentlessly with over 200 artists for two months without claiming wages to paint a wall of over 14,000 square feet in the traditional Mitihila style. Once considered as one of the dirtiest railway station in the country, it has now been transformed as the most beautiful and cleanest station. PRAKASH SINGH / AFP
