Personally photographed, slightly bad resolution because of the glass.
It's kept in Oplenac, the Karađorđević dynasty complex inside King Peter's house.
This rare photographic picture in January 1878, at the Pyramids of Giza, shows former President Ulysses S. Grant and former Confederate General William W. Loring -wearing Fez in the front- as the former was on his famous world tour, and the latter as inspector general of the Egyptian army and one of 50 Confederate and Union officers who were recruited between 1869-1883 by Khedive Ismael Pasha, to help modernize the Egyptian army.
In the book “ The Blue and The Gray on the nile” by William B. Hesseltine, it says that Loring told the local press that he was "delighted to welcome his old friend," and that the meeting brought back memories of "the old days when they fought together under the flag of the United States."
