In that collection are very rare photos from the Indian Mutiny years, all taken by a British photographer named Felice Beato. Explore the index for more photographs by him. (Oh, and just in case you want to get a grisly view of a Mutiny battle, look at this photo by Beato; courtesy: Wikipedia)
While googling for Beato, I found this interesting little tidbit about the man:
During his partnership with his brother-in-law, James Robertson, the pair photographed the Indian Mutiny. The pictures taken during this time during the 1850’s are thought to be the first to contain actual human corpses on the battlefield.(Emphasis mine; source: Wwar.com)
Lots of other pictures of interest in that collection, many shot by unknown photographers. Like this portrait called "Darjeeling Thief" or a portrait of a Tibetan doctor titled "Lama Doctor from Thibet (sic) - with human thigh bone trumpet, skull cup, and drum made of human scalps". You know you want to own a picture of a man carrying a drum made of human scalps.
One last thing. I was quite surprised by this photo of the Taj Mahal. What on earth happened to all those trees? (Space Bar, easy now.)
(Note: A Flickr user also has posted many of Beato's images. You may want to check them out on Flickr instead.)
