On the back it is stated to be an engraving "from the Original Photograph, taken August 23, 1863." Which is obviously the first picture in your post # 6. It is a
very close copy, down to some very small detail, while it is also quite a bit "cleaned up" -- it
may be something of an 1880's "photoshop" equivalent. Anyway, the engraver can't be accused of taking "Artistic License."
I wonder just when those bottom floors were whitewashed.
