Hadn't heard of a state publication, the Mexican Dept. of State puts out this
http://www.sre.gob.mx/tramites/consulares/guiamigrante/ "Guia del Migrante Mexicano" (also distributed free as a comic book insert in cheap popular Mexican periodicals of the same format).
The guide has been described as incentivizing illegal migration, however, it's common sense suggestions (be wary of "coyotes", travel after sundown in the desert, use a bit of salt or chlorine in your canteen, follow the telegraph or electric lines, walk on the side of the road facing traffic, avoid crossing freeways, telephones to consulates, basic signs and pictures of the uniforms, entities with which undocumenteds may have to deal) are all aimed at saving lives.
About 500 Mexicans perished crossing to the US last year, just a few were killed by dumb or excited gringoes, some simple instructions and pictures can save lives (even if "undocumented" ones).
