Denise Gripp, Vice President of the Iowa Genealogical Society writes: The picture is labeled, "Haworth Reunion, Sept. 28, 1905", and looks to have been taken in the yard of the Ackworth Academy, Ackworth, IA. It was found in a Roger Boone scrapbook housed at the Warren County Historical Museum.
Editor's Note: This is the only document that we have, pertaining to this reunion. We were able to scan the tiny document at a very high resolution to recover some of the details. Denise was especially intrigued at the child in the foreground, and what may be a "sun parasol".
