The Letraline set of 9 vintage Project-A-Line precision graphic tapes by Cornelissen is a specialized collection of tapes used in traditional graphic design and drafting. These vintage tapes were prized for their precision and reliability in producing clean, sharp lines and markings on artwork, blueprints, and darkroom materials. Cornelissen is known historically for supplying high-quality art and printing materials.
