The majority of photographs are undated and contain no identifying information apart from the photographer. Many of these photographs are featured in the Thedlow clippings scrapbook. Photographs by Samuel Gottscho appear to pre-date the other prints in the series by several decades and may document early Thedlow projects prior to Martin's employment with the firm. Clients include Mr. and Mrs. Herman Watkins (Palm Beach, Florida), Mr. and Mrs. William Chapman Foster (South Carolina?) and Mr. Harton Singer (Sewickley, Pennsylvania).
