Work in progress ... A historical collection consisting of unique documentation - letters, business cards and happy holidays, purchase and sales records - to reorganize and recondition, in order to ensure its preservation. After cleaning and unfolding the documentation, it was inserted inside of polyester bags, which protect and allow the reading of the document (front and back) without handling it. Subsequently, the bags were placed inside acid-free cardboard folders and finally inside acid-free cardboard boxes.
