After Saturday's win against Italy at the Aviva, O2 showed their appreciation for Brian O'Driscoll with a giant poster of the international caps record holder being held up by a giant balloon.
Here's a behind-the-scenes look at how it all happened.
Don’t forget to get involved in the #thirteen campaign by sharing a photo featuring either number 13 or ‘thirteen’ on Facebook, Twitter or Instagram, and include the hashtag #thirteen. Each submission will raise €1 for Brian’s chosen charities Temple Street and the ISPCC (up to €10,000).
