Recent advances in visual technology have resulted in a depreciation of the relative value of the photograph. A new type of photograph with some sort of psychological quality may be developed, however, by coating human materials onto a photograph, producing what we call a bio-memorial commodity. Among the various bio-substances that are regularly discarded, human hairs are especially suitable as starting material in this project, because they are peculiar to each individual and easily collected. Both Post-cast and soft Post-cast methods, developed in our laboratory, were utilized to convert human hair protein solution into protein films. We opted to use Print Club photographs as protein-coated samples, since they are available in large quantities and are of consistent quality. In consequence, the coating of human hair proteins on the photographs proved to be excellent in adherence and uniformity. While the protein-coated film prepared by the Post-cast method exhibited a whitish tinge, the film prepared by the soft Post-cast method produced great transparency. Proteins coated on the films remained decomposed, indicating the probability of long preservation. These results suggest the possibility of developing bio-memorial commodities which may offer important business opportunities.
