It was a tough job to treat this fragile, acid ridden, fractured support. The eyeglasses were easily removed but the paper was too damaged to withstand surface cleaning. The overall discoloration was much reduced with successive controlled pH adjusted baths, and the application of a lining of toned Japanese tissue and dilute wheat starch allowed the drawing to wrap around an acid-free board. The eyeglasses were reintroduced and secured on the verso with acid-free tape. The object can be now safely displayed in a vitrine.
