JW History in Pictures #1
Okay ... the second picture can be found here: http://pastorrussell.blogspot.com/2010/03/pastor-russell-at-carnegie-hall.html
I verified that this was indeed Carnegie Hall in Pittsburgh by comparing it to other historic pictures of the inside of the building.
The fourth picture can be found here: http://pastorrussell.blogspot.com/2008_09_01_archive.html I have searched high and low on the internet for confirmation that this is indeed a picture Russell's grave, but I couldn't find. I do believe that it is, though.
Incidentally, it appears that the blog where I found both of these pictures is written by a Charles Taze Russell apologist, but it does have some good historical information there.
