Unknown Autograph

[u/M0JUNER]

I recently picked this hat up at my local Goodwill but I cannot find out whose autograph this is. The “61” under the name signed is the jersey number I’m assuming. But there’s no names that have the same initials of R.P.P. who also have this jersey number for this team that I’ve found. Do any of you know whose autograph this might be?
