Back in the ’70s a young man known as the “Handshake Kid” snuck onto the ice and shook hands with Boston Bruins players after the Flyers won the Stanely Cup in 1974. Now some Flyers alum are trying to identify the man.

Former Flyer Brad Marsh tweeted about The Handshake Kid mystery.

Marsh said whoever can identify the man will get an autographed Flyers jersey and a phone call from former Flyer Terry Crisp.
