I think the rest of the film title refers to the "man in the silver mask", but my Spanish is not that great. Apparently this guy "Santo" was quite a popular figure in Latino wrestling history. Beats me. In any case, it's certainly an interesting car. I can't help but wonder if it was actually done by a coachbuilder (Serra, perhaps?), or if, as I said, it was done by the studio? Does anyone know more about it? In any case, another great puzzle where, as usual, the search was more than half the fun!
