The 1,308 figure comes from the amount of special rattle tickets brought by City supporters before the Scunthorpe fixture.
When fans arrived at the game this Saturday wearing a Christmas jumper, they were given a raffle ticket as they entered the ground.
At full-time, supporters taking part were then asked to stay in their seats for a photograph before the club conducted a raffle draw to see which lucky fan won a free season ticket for next season.
The winning ticket was (White) number 596 (ref AS1P DK4X)
The raffle ticket stubs and photographs will be used to help confirm whether or not the record has indeed been broken. As part of the event, the club also asked supporters to donate £1.00 to bucket collections around the ground, with all funds going to Bradford Hospitals Children’s charity.
Supporters can still get involved by tweeting pictures of themselves in their Christmas jumpers to @officialbantams using the hashtag #GetYourJumperOn
