First day at Odessa Historical Foundationin Delaware. I had a tour of the historic houses, met the director, learned about the history of the foundation itself, and met the maps I'll be working with. Most are very brittle and discolored. The first I'll be working on is of Delaware and Virginia made in 1795. Today I wrote the condition report and treatment proposal, which will involve removing a cardboard backing that was added after the map was removed from binding. The cardboard is highly acidic and has had a major role in causing discoloration in the paper. I started today by doing color fastness testing on the watercolor and gouache (they seemed fine, though the gouache was red lead and will probably flake off if agitated), and did some light mechanical cleaning using a vinyl eraser, making sure to avoid areas of color or fine detail.
