This is a group photo of the staff of Cope & Stewardson, circa 1899, where JOB served as draftsman. Is one of these fine moustachioed gentlemen our James?

Edit: The photo actually has a caption, buried on another page:
From Left to Right: Alfred Morton Githens, William Charles Hays, Walter Cope, John A. MacMahon, James O. Betelle, Emlyn Stewardson, S. A. Cloud, Wetherill P. Trout, Herbert C. Wise, James P. Jamieson, Eugene S. Powers, E. Perot Bissell, Miss Louise Stavely, Charles H. Bauer, William Woodburn Powers, John Molitor, Camillo Porecca, Office Boy, C. Wharton Churchman

So he’s 4th from left, back row.
