In all honesty, they probably didn’t know it and didn’t think much of it. But now that we know who created it and that he never got compensation, what is the best approach? It’s up to the artist on what they want to see with it, but I do wonder how many more of these cases happen that we just don’t pick up.
Goalie masks are unique in a way because they aren’t required to put just the team logos on it. They can be creative and artists can put whatever they want to the mask. In fact, sometimes the mask has nothing to do with the team, but the design reflects the player.
So with this, it might open up a new way of artist and players in approach to the goalie mask designs. These cases are rare so we might not see it much. But when it does happen, I hope the artist is contacted and properly compensated. They deserve that at least.
