The front board was reattached, after sewing back in the loose sections using an aerolinen flange backed with hahnemuhle. A piece of toned leather was then adhered to the inside of the spine, and to the boards. I was able to very slightly lift the original leather along the joint so that the new piece should slide underneath. Then the leather was turned in at head and tail.
There were a few more areas of paper repair to finish, and a bespoke corrugated board box lined with plastazote was made. The box included some small fragments of the text that I couldn’t find places for, as well as the documentation and handling guidelines.
