Mexican-American artist Emmanuel Valtierra studied Graphic Design in the University of Nuevo Leon (UANL) and Photography in San Antonio College. After some time, he adopted the aztec codex style for most of his works bringing him attention from the public and press.

To establish himself as a "tlacuilo", he released a series of pop culture images, playing cards, and book. All with Aztec style.

The love Valtierra has for history has influenced him on all his projects. The goal is to keep teaching new generations about our past in a fun way in every media possible.

Some of his most populare releases are: Codex Valtierra (sidewise award), Codice peregrino (white raven award), Aztec tarot, Blue beetle #1 (DC comics variant cover art), and many more.
