Edition dedicated to the art production from 1994 to present days of conceptual artist Marcos Ramírez (b. Tijuana, Mexico 1961), known as "ERRE". He is the creator of large-scale public installations with strong messages of political and social consciousness and cross-border physical, economic, linguistic, and cultural boundaries. "This essay highlights a series of crossroads or intersections in Marcos Ramírez ERRE's artistic sculptural approaches where site and content come together and overlap. These crossings between a variety of objects are identified neither by chronological order or thematic affinity. Rather a look through his entire oeuvre that exposes an evolution that begins from strategies created in the public domain for large-scale art works.
