Petro Photoglyph...A photo engraved stone. The technology to inscribe hologram messages onto the surface of stone appears to be similar to the fabrication process that yielded The Virgin of Guadalupe. The technology required to decipher or translate the hologram images from both petro photoglyphs and The Virgin Talma, requires a visual environment of selective spectrum illumination.
