Poor of Victorian London Photos

The following photos were taken by a man named John Thomson in Victorian London during the early- to mid-1870s.  These photos were originally published in a magazine titled Street Life in London in 1876 and 1877.  Today, the auctioneer group of Dominic Winter sold, at public auction, a book with 36 photographic plates taken by John Thomson.  The book sold for a little less than $16,000 - or, for 10,500 pounds English.
Thanks to NBC news, here are a few of the photos, with their original titles:
