Moroc... Les tresors du royaume, edge to edge doublers.
The doublers are hand printed and dyed with the same dye stuff used for the leather with a gentle covering of bookbinders varnish. That way there is a narrative between the outside and the inside of the book. I love the way in which the doublers join everything together.
The contrast between the doubler ( on the left ) and the endpaper ( to the right ) can be seen and I also hope the mirror like aspect.
