Here’s a poster restoration and linen backing project for an Australian Daybill Lolita (1962). Now looks pretty good considering the heavy Foxing which affected about 95% of the poster.
The trick was spot bleaching before local Bleach bath. It’s a bit harsh/risky on the paper, but the stains was so heavy. Basically I went over each spot with a drop of stronger bleach to minimize the staining.
Still, after the poster was dry the was some staining left along the borders. So a light brush using a mixture of Golden conservation colors and Synchromatic transparent aniline dyes ( water colors ) toned it down pretty good along the borders.
And here is the completed project:
