Photographs and negatives are a very important and large part of the Klinger papers, and they are predominantly photos of family and friends coming from veritably the entirety of the 20th Century: the series goes from Walter and Hertha's childhoods, through their friendship and dating years, then their emigration from Germany and Austria, the war and their first years in America, to trips to Europe and then retirement, and every family photo sent to them in between. Originally found mostly in a flatbox and without organization, the photos have been organized according to date and those without dates have been grouped together.
