Last known picture of Abraham Lincoln

[STS Lincolnite]

Is the photo which Mr. Warren took of Tad known and published?

And at what place "outdoors" exactly was President Lincolns photo taken? Some accounts say on the balcony at the southfront of the White House. But, was there in 1865 a balcony? Was there a balcony at all in 1865? I thought the only balcony is the Truman balcony.

I think the photos were taken on the north front. If the photos attached are what they claim to be that makes the most sense.

Also attached is a photo of Tad taken by Warren at that time.
