While in rough shape, the interiors of this book were quite nice and flexible - although, torn and well-read.  Pieces were missing from not only the cover but the interiors as well.  Restoration began by removing the staples and separating the folios.  The cover and interiors were dry-cleaned to remove any surface dirt and the entire book was humidified and pressed to flatten the folios out and remove the spine-roll.  The cover was treated with solvents to remove the written ink and the ink-stamp from the cover.  The remaining stains (both on the cover and interiors) were then removed through bleaching of all the folios.  Areas of loss on the cover and interiors were spot-cast (a form of leaf-casting) by hand.  All infilled areas of the cover and interiors were then color-touched to recreate missing artwork and graphics.  The inside front cover text that was damaged (and missing) was recreated as well.   The book was then refolded,  reassembled and pressed.
