70s issues of the Mexico City lucha mag El Halcon featured pull-out 11×17″ posters of current ring stars. They were poorly printed, on super thin low-grade newsprint, and featured photos that were never that good to begin with. However, these are now invaluable as snapshots of the time, with as many now forgotten and obscure masked performers as there are legends.
I was lucky enough to score over a hundred of these from a Tijuana/SoCal connection, so they’ll show up from time to time here for years to come. I like honing in on certain guys or cutaway details, rather than scan the whole (often lousy) layouts.
