Signum creates high quality products characterized by strict hand production, quality of the materials and refinement of the design. In the last decade we mainly focused on the production of leather and paper bookbinding articles, always keeping alive the link with the techniques and materials of the past, with the wisdom of the historical artisan tradition achieved thanks to our master bookbinder, a skilled craftsman who increased his art and knowledge during long periods of activity as a restorer for the National Library of Florence.
