Claire Falkenstein's *Untitled* and *Structure Graphica* exemplify her pioneering exploration of open-form sculpture and drawing, where tangled, web-like networks of line and material dissolve the boundaries between two and three dimensions. Her gestural, improvisational marks evoke a sense of endless expansion, reflecting her deep engagement with mid-century avant-garde ideas about space, energy, and interconnectedness. The works embody Falkenstein's belief that structure should feel alive and in perpetual motion, as if caught in the act of becoming.
