Well I'm at a loss.
If the man himself says it isn't him then I don't know who it is.
Did he see the card? We know Bernie wasn't there for the 72-73 playoffs and I still believe that photo predates that series.
Belhumeur played in 10 minutes of the playoffs and Favell played the rest. Bobby Taylor did not see action.
If you look at every goalie who could have played for Philly from 1967 to 1973 it is a short list.

That mask is referred to as the Ghost mask and I don't know of any other NHLer let alone Flyer who wore that other than Parent.
Favell wore a Higgins mask as did Taylor. Favell only wore #1 with the Flyers
McLeod wore a Higgins as well and Gamble had a Fibrosport. Belhumeur's mask is a Lefty Wilson
The equipment certainly looks like Bernie's on that card
The Sher-Wood stick (black tape with corner of blade exposed) the Cooper blocker and glove
If you look at the puck marks on the blocker (dots - row 3) and lower left corner you can see similarities.
Also it is hard to see but there is a puck mark on the bridge of the nose and over the right eye on the mask
Here are my photos of Bernie is the ghost mask
and the card again
I certainly think there is some evidence there but I will not argue with a legend like Bernie Parent. Maybe it's some unknown tryout in a preseason game, I really have no other ideas on who it could be
