Does anyone recognize the reportedly Mexican artist’s style, this painting’s origins, or its source?

Leave a comment if you have any information on this one, please.

Red Pill Junkies writes: “It seems to follow the usual pulp fiction art of Mexican comics and calendars of the 1970s —with voluptuous women endowed with gravity-defying bosoms. So my first guess is that it was done by someone working for those kind of publications, like El Libro Vaquero —a very old and successful comic-style booklet that is still in print to this day.”

“The pose of the two figures reminds me a lot of the art inspired by the legend of Popocatepetl & Iztaccihuatl — an old Aztec legend that referred to the two volcanoes that surround Mexico City.”

“Grandeza Azteca” or “La Leyenda de los Volcanes” by Jesús Helguera.
Thanks for suggestions from Mexico’s RPJ/Miguel.
