Bittersweet Harvest, a bilingual (English/Spanish) exhibition from the Smithsonian, explores the little-known story of the Bracero program; the largest guest worker program in U.S history. Between 1942 and 1964, millions of Mexican men came to the United States on short-term labor contracts. Both bitter and sweet, the Bracero experience tells a story of exploitation but also of opportunity.

This exhibition is organized into three main sections that explore the braceros’ motivations and expectations for the journey north, the work they did and the effects the Bracero program had on family and communities in Mexico and the United States. “Bittersweet Harvest” features the work of famed photojournalist Leonard Nadel as well as oral histories collected by the Bracero Oral History Project. The exhibition was organized by the National Museum of American History in partnership with the Smithsonian Institution Traveling Exhibition Service and funded by the Smithsonian Latino Center.

It runs from Sept. 10 to Nov. 15.
