The artist is Oswaldo Guayasamin. My father had this painting since I was a kid. Him and my mom lived in Colombia before coming to US in 1970. It has been kept rolled up in a rolling tube for many years. I don’t k ow if it’s an original or not. I do know my dad’s family frequented Equador in the 60s and 70s
