On June 13, mates Dave Gibson and Guy Lovell will don some questionable lycra and join the annual Fireflies Cycle Tour to tackle some of the most gruelling climbs of Le Tour de France.

Their mission – to help raise money for leukaemia research and treatment.

To garner awareness and help raise money, Dave and Guy are offering a special service to the advertising community in Australia. For a “delivery fee”, the ‘Cannes Couriers’ will deliver your questions to four of the industry’s most admired luminaries, who will be at this year’s Cannes Lions International Advertising Festival. Each luminary will write a handwritten response to their favourite question, before the Cannes Couriers personally deliver each letter back to that person’s agency.

With letters being such a precious yet lost art of communication, they’re sure to serve as special keepsakes between you and some of the true legends of the industry.

A big thankyou to the luminaries for their valuable time, as well as all of the sponsors for their support.
