Signed Ottawa Rough Riders helmet

I have yet to take an inventory of all signatures - but made sure to take the photos from all sides so that every signature is visible. I have no idea of it’s value, but have sent in an appraisal request as well as spoken to the CFL alumni organization on Facebook where I was told that it looks to have been signed at an alumni game 10-15 years ago.
The underside says 2001 and definitely looks to have had some game play, so that analysis makes sense to me .
