Letterproof Alphabet in Stone - Historical Dutch Type Design Poster #1350206 (License: Personal Use)

This poster presents the “Letterproof Alfabet in Steen,” a conceptual type system developed by Dutch designers Dom Hans van der Laan, Willem Noyons, Maarten Bullemeier, and Rob Stolte. It illustrates four progressive stages-Grundfiguur (basic geometric units), Contour (outline forms), Hartlin (solid strokes), and Drukletter (final printed glyphs)-alongside a set of typographic punctuation marks. The design reflects mid-20th-century rationalist typography and modular construction principles.

Used in design education, typography archives, or museum exhibitions to illustrate systematic letterform development; appeals to graphic designers, historians, and students researching Dutch modernism and structural type design.
