Queens-based artist Esteban Cabeza de Baca’s parents met while working as union organizers for United Farmworkers founders Cesar Chavez and Dolores Huerta; in Cabeza de Baca’s colorful narrative paintings at Garth Greenan Gallery in Chelsea, he pays homage to both family and labor history. Here in ‘Huelga,’ or ‘Strike,’ Chavez and Huerta walk down a row of grapes, a reference to a nation-wide boycott of the fruit led by the duo as they fought for fair wages and decent working conditions for farm workers. (On view through July 21st).
