It's safe to catch and keep this dolphin - a Dan Marino signed full-size, non-replica Miami Dolphins helmet.
This heavyweight "L" Riddell helmet features full interior padding and complete chin strap. Marino signed the upper portion with a black marker, and the authograph is full guaranteed by an Upper Deck Authenticated sticker and matching cert card. The signature does show some ink loss and would likely grade out in the ("5-7") range.
