Amitabh  had asked his fans to join the journey of `Te3n`, which releases on June 10, by coming up with innovative ideas to promote his film (through posters, videos, poems, games).  Winners from across the country were honoured in a special ceremony . Big B and Vidya interacted with the winners as their entries were put on display.
