Many people collect them for looks or because they are avid sports fans.Other people collect all kinds of protective masks, in fact, we have on this site a category for these. What fascinates me is that this kind of safety equipment is also meant to intimidate opponents.
Goalies Bernie Parent and Pelle Lindbergh were famous Philadelphia Flyers who introduced the very scary fiberglass face mask. This one was probably wore by Pelle. Others were a little different and often colorfully painted.
