Looking at the cross currents of historical and contemporary events
I don't know where to put this photo but guarantee you will be startled to see George Armstrong Custer and friends in a new light:http://img10.imageshack.us/img10/7900/95108997.png
That looks like Nathan Bedford Forrest to his right. Do you have any info to go with the photo, trip, you can start a new post.
Amazing photo -- usually these colored ones look artificial, garish even. The power of the computer. I assumed it was a Matthew Brady photo but I was wrong. It was someone named James Gibson: http://www.sonofthesouth.net/union-generals/custer/pictures/custer-fitz-porter.htm
Regret I don't have more info. But I believe that's Custer with the pooch
