In this example we had numerous acid burns resulting from masking tape which had been used to repair small tears along the margin. We had to remove the stains using a solvent and then re-match the color of the margins with watercolors. Fortunately the image itself was fine and needed nothing. An example of a Tier 2-Tier 3 restoration. Original condition of this poster was a C4-C5 Restoration has improved the overall appearance a lot – well worth undertaking for popular poster!
