Greater Mexico refers both to the geographic region encompassing modern Mexico and its former territories in the United States, and to the Mexican cultural diaspora. Exhibitions of visual and material culture from greater Mexico have played an important role in articulating identities and affiliations that transcend limited definitions of citizenship. Following an introductory text by Jennifer Josten, five scholars offer firsthand insights into the intellectual, diplomatic, and logistical concerns underpinning key border-crossing exhibitions of the “NAFTA era.” Rubén Ortiz-Torres writes from his unique perspective as a Mexico City–based artist who began exhibiting in the United States in the late 1980s, and as a curator of recent exhibitions that highlight the existence of multiple Mexicos and Americas. Clara Bargellini reflects on a paradigm-shifting cross-border exhibition of the viceregal arts of the missions of northern New Spain. Kim N. Richter considers how the arts of ancient Mesoamerica and the Americas writ large figured within the Getty Foundation’s 2017 Pacific Standard Time: LA/LA initiative. Xóchitl M. Flores-Marcial offers insights into productive institutional collaborations with transnational Indigenous stakeholders, focusing on two recent Southern California exhibitions of the Oaxaca-based Tlacolulokos collective. Luis Vargas-Santiago discusses how Chicana/o/x art entered Mexico City’s Palacio de Bellas Artes in 2019 as a crucial component of an exhibition about how Mexican revolutionary Emiliano Zapata’s image has migrated through visual culture. Together, these texts demonstrate how exhibitions can act in the service of advancing more nuanced understandings of cultural and political interactions across greater Mexico.
