Riddell Raiders miniature football helmet, signed in black marker by the legendary Bo Jackson.

(This is the old-style helmet with round ear holes — same style Jackson wore when he played).

Signed at an official paid private autograph session.

Authenticated by independent third-party authenticator Beckett Authentication Services (their numbered tamper-proof QR code authenticity hologram is affixed to the helmet, and it is registered in their online authenticity database for easy proof of authenticity).
