Scope and Contents: This collection consists primarily of photographs that Walter J. Binder took or acquired while serving in WWI. Binder served with the 487th Aero Squadron of the Army Air Service, Allied Expeditionary Forces. Printed material is comprised of official forms of enlistment and discharge as well as notes on postcards and the backs of photographs. Some photographs are captioned (presumably by Binder) but otherwise there is little to identify the location or contents of photographs. All other information given on these photographs is from research conducted by the staff of the University Archives, and is subject to change or correction as needed.
