This non cabinet card photograph features a portrait of a class from a Cuban school. The photograph was taken during the 1936-1937 school year. The children are multi racial and all boys. There are three teachers evident in the photograph. Note the math problems written on the blackboard. The photographer is J. R. Betancourt. I do not know where in Cuba Betancourt operated his studio. “10 de Octubre 618” is likely the street address of the studio. “10 de Octurbre” is a national holiday in Cuba. The day is known as “Grito de Yara” and it commemorates the 10 Years War (1868-1878). The war was fought to gain freedom and independence from Spain.
