Looking for help identify Hawks autograph

I was born in a small Northern Ontario town called Capreol. Doug Mohns’ (who played for the Chicago Blackhawks) family were friends of our family as he was from Capreol.

In the mid 1970s when I was a kid,I was gifted this picture from Doug Mohns of the 1967 Blackhawks with a number of autographs on the back.

I assume they are legitimate, but I could be wrong. I am having trouble identifying 1 of the 18 autographs on the back.

Here is the list of autographs that I can figure out:

– Billy Reay (coach)
– Bobby Hull
– Phil Esposito
– Glenn Hall
– Pierre Pilote
– Pat Stapleton
– Eric Nesterenko
– Ken Hodge
– Ed Van Impe
– Doug Mohns
– Wally Boyer
– Lou Angotti
– Don Uren (Equipment Manager)
– Matt Ravelich
– Ken Wharram
– Denis DeJordy
– Doug Jarrett

I have highlighted the autograph in the 3rd picture that I am stuck on. I would appreciate any help and any other thoughts on autograph legitimacy.

Thank you.
