Now that the book was in two distinct pieces he needed to create an enclosure to house them both safely. He decided to create a two-compartment box, one to hold the new rebound volume and the second to house the original vellum cover. The original cover was supported by a piece of foam cut to the size and width of the original cover and covered with Tyvek to prevent abrasion. He even created a space in the support block to house an envelope filled with other small pieces of the binding that needed saving. With the original cover supported he then made a chemise using Tyvek lined linen to protect the cover.
As you can see the finished product is something to behold and in my opinion a very effective box for its purpose. Bravo Tony!
