My mom grew up in El Salvador and when I became a fan as a kid, she told me Mil Mascaras would regularly appear at shows in her neighborhood. I got more and more incredulous the older (and "smarter") I got. Eventually during a trip to my grandma's house she produced a photo of her and "Mil Mascaras" who seemed to be a good 100 lbs heavier and 6 inches shorter than the true article. I broke the truth to my mom, aunts, and uncles and surprisingly they weren't bothered - in their young minds they had seen the legendary Mil Mascaras and even the revelation that it was probably the butcher down the street did nothing to tarnish the memories.
As an aside - are there any good resources for wrestling info in latin America? Aside from Titanes en el Ring from Argentina and Las Cholitas from Bolivia I haven't seen much online regarding the region. I seem to remember reading about Brazil having a scene in the 70s or 80s.
