England international and Arsenal midfielder Jack Wilshere has teamed up with Topps Match Attax to support this year's Sport Relief campaign.
500 special edition Sport Relief cards signed by the player are being inserted into lucky packets of the 2014 edition of Match Attax Extra.
For every signed 'Jack in the pack' found and registered online at www.toppsfootball.co.uk, Topps and the Premier League will donate £100 to the charity.
"Every autographed card will contain a unique code for lucky collectors to enter on the Topps Football website, which will enable us to make a donation," said Rod Pearson, marketing director for Topps. "As such, we are urging collectors to keep their eyes peeled for these special edition cards and register them as soon as they find them.
"Thanks to our partnerships with Jack Wilshere, Sport Relief and the Premier League, we're pleased to be offering fans and collectors alike the opportunity to play their part in helping to raise valuable funds for the charity, as well as the chance of getting their hands on an exclusive, signed card too."
