I'd be interested to hear anything further you might uncover, vayapues.  Perhaps this thread can stand as a conduit for information on Mexican make-up artists.

I've seen many of the films listed but while compiling these names and credits I discovered a whole bunch more I'd like to see.  I was reminded that I had seen PUSS 'N BOOTS back on a kiddy matinee.  I'm really curious about the Tom Thumb films.
