Philipp Grubauer 2020-21 Mask

 Philipp Grubauer of the Colorado Avalanche (born November 25, 1991 in Rosenheim, Germany.)

Artist: David Gunnarsson

Grubauer wore multiple masks this season. This is the first I saw:

This is the mask he wore with their reverse retro jerseys (going with the Quebec Nordiques logo.)

David Gunnarsson also listed this mask for this season, but I haven't found any game photos where he's wearing it.

He had a Hockey Fights Cancer mask he wore one game in March.

David also posted this mask art, but I didn't see any game photos with it either.

Jack Campbell 2020-21 Mask

 Jack Campbell of the Toronto Maple Leafs (born January 9, 1992 in Port Huron, MI.)

Artist: David Gunnarsson

Campbell has worn two masks this season.

I haven't seen as many in-game photos as this one, but I believe it came a little later in the season.

Tristan Jarry 2020-21 Mask

 Tristan Jarry of the Pittsburgh Penguins (born April 29, 1995 in Surrey, BC.)

Artist: Dave Fried (Friedesigns)

This is Jarry's first mask of the season.
