This a photo taken from our round the world trip and was taken using 35mm film. We were very lucky on that day. The train graveyard is quite a way outside of Uyuni itself and somebody on this occasion had taken some white paint, a considerable amount to paint an Albert Einstein formula on the side of this train. This must qualify as an entry for the most intelligent graffiti ever done. It is available as a blank greeting card and various types, sizes and formats of images.
