The other special exhibit at the Palace of Fine Arts consisted of a single work, "Xibalbá, the Mayan Underworld". This mural was done by Guatemalan-born painter Rina Lazo. It was her last work of art, completed in 2019, the year that she died at the age of 96.
Lazo was influenced by the Mayan people of her homeland. She moved to Mexico where she was a student and assistant to Diego Rivera. She worked with him on some of his most famous projects. After Rivera's death, she continued to do mural paintings on her own and is considered an important figure of the muralist movement.
The artist joked that she left the self-portrait for last because she did not want death to take her before she finished the mural.
