Mark Kelso

I got a quick return over the holidays from Mark Kelso.  He appearing in four consecutive Super Bowls with the Bills from 1990 to 1993. He was well known for wearing a "pro cap" on his helmet which was used to reduce the risk of concussions.

Remember these?

I know the auto is hard to read, but it says, "God Bless You, Mark Kelso, #38."  It's not signed in ball point pen, but a thin blue marker.
