For family history researchers and for anyone investigating  the history of photography the back of a Victorian photograph can be as interesting as the front. 

Find the front of any card click  on the filename in the tag  list . (If there is a photo of an album page that will show too). Any of the filenames will do the job, for example DrBuckby01F. 

Not all cards have the name and address on the back, for some its only on the front so you will see some photos here too.
