Team Unicorn members Andy 'The Hammer' Hamilton and Colin 'Ozzy' Osborne took time off from their busy professional commitments to visit darts specialists Mad on Darts at their store in Lincoln.
There was a great turnout with players of all ages wanting to play them and have cards and shirts signed.
“We had players from local teams and quite a few youngsters who wanted to meet their heroes that they have seen on TV and the event has further raised our profile in retailing darts," said Rick Haslam from Mad on Darts.
Unicorn Sales Director Richard Lowy said: “It was great to see the enthusiasm for two such popular members of Team Unicorn at one of the top UK dart retailers."
