Reason: Loan
Description: Objects surface cleaned with brush then with chemical sponge and Staedtler eraser crumbs avoiding image area. The eraser crumbs were only used on recto edges. The media on both objects was tested with cold and warm water. The signature and ink stain did not test positive with iron (II) indicator strips suggesting nor iron gall ink. Objects humidified in cedar wood chamber (capillary matting, Gore-Tex) then washed in subsequent baths of warm water. Warmer water was applied locally with a brush to foxing and dark areas of discolouration between baths. When in the bath the water was agitated with a brush around foxing and dark areas of discolouration. The debris/strips were able to be peeled away with spatula and residues reduced with cotton wool swab between baths. Tears and weak areas supported with Japanese tissue adhered with wheat starch paste. Infill (1866,1114.804) carried out with one of the patches that was removed in washing with a tissue backing. Accretion on 1866,1114.804 reduced by dry scraping. Objects humidified (as before) and pressed between felts.
