I used organic solvents, laponite poultices and a suction disk to remove oxidized tape carriers and reduce tape staining, after which time the solvent residues were neutralized with blotter washing. Using Japanese tissue, wheat starch paste, BEVA D-8 and cellulose powder, I was able to reinforce weak corners and edges and filled a small loss. The drawing was flattened and all fills were toned with watercolor in distilled water. All in all, it was a very time consuming process, but one that paid off as the drawing was stabilized and the amber-toned, distracting tapes were much reduced with treatment.
