Efraín Enrique Recinos (born may 15, 1928 — died october 2, 2011)
I've yet to find any of his work with titles or dates attached, it varies from painted murals, to mosaic and sculptures - some of them adorn government buildings in his native Guatemala. The murals have a mixture of inspiration some of them with aspects of the modern world but in the style of ancient Mayan carvings, with humans rendered in simpler geometric forms.
Wow, this is awesome.
