What are your favorite luchador masks?

Title pretty much says it all, just list and/or provide pics of what your favorite luchador masks are from any company in wrestling, past or present.

I like a lot of simplistic, classic, luchador masks. Fishman comes to mind. It's like the stereotype for what a lucha mask looks like. Dos Caras has a pretty neat, yet simplistic, design. I like El Hijo de Fantasma's mask (The one in Mexico, not the garbo throw away NXT one) with it's open chin and cat eye frames looking eye holes. I also liked his Cuerno mask. Simplistic and classic, but still complex and original. The seldom worn combo mask of the two gimmicks was pretty fly too, and I think that's the picture I'll actually post.
