Top Trumps is preparing to launch a new London pack based on 30 things to see in the capital.

Planned to arrive in stores this summer, the launch will be celebrated with a themed treasure hunt across London on a classic Routemaster Bus.

The city-wide treasure hunt will see bloggers, opinion formers and press along with their kids to view some of the capital’s iconic structures and features, ending with a stop The View from The Shard.

“Generating real time social media buzz around the new pack launch, the event is designed to immerse the media in all things London-centric,” said Emma Arthur, director of Norton and Co.

“Top Trumps is an established brand with a strong heritage among both kids and parents and we feel privileged to be working on such an iconic pack theme.”

Suzie Howes, marketing director of Winning Moves, added: “It will be great to see the attractions brought to life via a media treasure hunt designed to immerse the press in the Top Trumps brand.”
