According to luisfi61.blogspot.com, this is a fellow named Andy ( a professor of law and economics) sitting in front of his Maximon altar. As the blog succinctly notes, “En todo buen altar para Maximón no deben faltar el güaro, los cigarros, las candelas, perfumes, polvos, amuletos e inciensos” — every good Maximon altar must include guaro (a vodkalike drink), cigars, candels, perfumes, dust, amulets, and incense.
You can find more about Maximon here, together with my own photo of a Maximon altar.
