Not sure how familiar may of you are with older goalie masks, but here is a slideshow of some of the best goalie masks of the late 60s, 70s, and early 80s. Some of the designs really show how eccentric NHL net minders really can be. For example here is an explanation of Gillies Gratton's lion mask:
"A revolutionary design by Harrison, this snarling lion was created for Gratton, a Leo and firm believer in astrology who one night informed his coach he could not play because the stars were not properly aligned."
I also watched an hour show on Versus that discussed the creation of goalie masks (Jacques Plante) and had Kevin Weekes give interviews of older goalies who had played with and without masks. The title of the show eludes me now, but I definitely found it quite interesting. Anyways, hope you enjoy.
