Over the last week, the club gave away Mariners-themed Santa suits as well as beard and hat sets to fans.
Now we need those supporters who claimed their fancy dress items to join together for a festive photo to help promote the club's games over Christmas.
The club, in partnership with the Grimsby Telegraph, are asking fans, dressed in their best festive gear, to visit Blundell Park's ticket office tomorrow lunchtime at 12.30pm to star in a special photo.
That photo will be used in the Grimsby Telegraph this week.
All fans that turn up will receive a free A3 Mariners Legends calendar worth £7.99 – it would make a great Christmas present!
Accounts manager, Steve Wraith said: "Quite simply, we have the best fans in this league by a country mile.
"We're hoping that plenty of them will turn out tomorrow lunchtime for this special photo."
