One of a kind package directly from the originating Industrial Designer/Inventor's estate and includes original photos, concept drawings, technical blueprints, photo slides, patent drawings and paperwork, original ads for the finished products and more. See our pictures for an idea of the sheer size and completeness of this piece of typewriter and design history. Most but not all pieces are shown. Some items are rolled, a couple have hanging pinholes in the corner. Two blueprints have some damage as shown but are solid otherwise.
