Christo's "Wrapped Staircase" is a collage that combines fabrics, staples, string, and graphite to visualize his concept for wrapping an architectural element at the Rue de Paradis location of Yvon Lambert Gallery in Paris. The work exemplifies Christo's signature approach of creating preparatory studies that document his large scale environmental interventions through mixed media on paper. Presented in the artist's distinctive Plexiglas box frame, the piece functions both as a planning document and an autonomous artwork that invites viewers to imagine the transformation of everyday architecture through textile concealment.
