Above is a photo I found online while browsing images, showing the second prototype for the famous Jacques Plante medium size Fibrosport Elite street mask, on which the Jason mask was very closely based. This mask remained in the office of Jacques Plante, the man who invented and popularized the modern goalie mask, for many years and was auctioned off in 2007 by his heirs. The medium mask, which the Plante company of Magog, Quebec, Canada also made for American companies Cooper and Rally, was catalog number 653602. The Cooper version was also known as the hm7.
The major differences between the original Plante design and the Jason mask was in fabrication: the Plante mask was made of a sturdy fiberglass resin and was relatively thick: the hockey masks made for Friday the 13th part 3 were pulled in clear acrylic and were very thin and brittle. The Plante mask, which commonly had a back plate to attach the five straps to for extra security, also had padding on the inside so the mask didn't crack your face open like an egg if you were unlucky enough to be hit by a puck. The masks made for the Friday the 13th series were also somewhat more crudely fabricated: the discriminating eye will notice mold chipping around the eyes and other anomalies that make the Jason design really unique.
The Plante masks, which were made from the late 1960's until the company closed its doors in 1976, were made in a very wide variety of styles and customized versions that fit your face perfectly were made as well, mostly for professional ice hockey players. The "street" mask that became iconic outside the hockey world in 1982, was available in white or beige and retailed for fifty dollars.
