Class of 1929, black and white photograph print (developed out process).
This documentary photograph from the University Archives was conserved in 2012. The photograph had a brittle support and had split in half, due to the emulsion fighting with the support over a long period of time. Heat and humidity had also caused chemical and mechanical decay. Conservation for this photograph included: surface cleaning; removal of tape from the back of the photograph; reattaching the separated halves; mending tears and filling in losses with Japanese paper and wheat starch paste; consolidating losses and lifted areas with gelatin solution; humidification of the print; and hinging the print into a window mat.
