The Mexican artist Felipe Ehrenberg (b. 1943), has worked in a variety of artistic modes that include the interstices between movement, urban space and sculpture. Topology of a Sculpture documents a walk made by the artist one London afternoon. True to his connections with mail art and Fluxus, Ehrenberg stopped at five different points in order to mail postcards. This enabled him to question the static nature of sculpture in public, opposing it to far more and ephemeral notions of what sculpture can be.
