The elaborate decoration of the binding shown above has not been accomplished by the application of many small individual tools, but rather has been accomplished by the use of a single large plate or 'plaque'. Gold tooling by plaque is thought to be the invention of Pierre-Paul Dubuisson and his father, Rene, who specialized in the binding of almanacs.
This example is found on Plate 37 of the 1910 Paris publication entitled LIVRES DANS DE RICHES RELIURES by Édouard Rahir.
