“The Indexical Design Symposium explored physical trace and its role as an expression of evidence, so in this poster, we conveyed indexicality—the causal connection between an object and its effects in the real world—by rendering the title indirectly, as a trace of itself, showing only evidence of its existence. We made the poster letterforms physical by generating them as stencils that were then overlaid on cyanotype paper and exposed to the sun.” 23½ × 33, 4-color, offset.
