According to the book Arte Naif: Pintura Maya Guatemalteca Contemporanea, Vicente Simaj Yat comes from San Antonio Ilotenango, Quiche, Guatemala.
 

Don Margarito Vicente Simaj Yat began developing his skills with strokes and colors in 1970.

In his beginnings, he elaborated drawings on postcards, to sell them on the streets of the Capital City, where he moved from his native Quiche.

Later, he studied at a painting academy and moved to canvas, with which he produced new works, with an improved technique, which he presented in an art gallery.

At present, he continues to create beautiful works of art; which can be admired and purchased in his bedroom house, in the Municipality of San Antonio Ilotenango. His specialty in painting includes: Landscapes, portraits and prints of traditions of San Antonio Ilotenango.  (per Facebook post by Cooperativa Santa Cruz RL)
