Millie, 12, and Gavin, 10, have joined stars such as Diana Ross and the Jackson family in an unusual work of art.
The Moyross siblings, who are still undergoing medical treatment and skin graft operations after the 2006 horror attack, were given the honour of placing the last two dots in the spectacular portrait.
Los Angeles-based artist, David Ilan, commenced work on the ‘dot’ portrait four years ago.
Travelling around the world with the work, tens of thousands of people have been invited to place a dot in the artist’s outline.
Millie and Gavin completed the dot work when David visited Dublin at the weekend.
The artist was introduced to the Limerick children by plastic surgeon Dr Patrick Treacy.
The artist said: “It was very special and meaningful. We just wanted it to be low-key. I didn’t know anything about the Murray children before but, when we heard about them, we knew they were the right people (to finish it).
“They received the very last dot from all the millions that have been placed on the portrait.”
When Michael Jackson had been in Ireland, he repeatedly asked about Millie and Gavin having discovered what had happened to them during a petrol bomb attack on their mother’s car.
David said: “We have been told Michael cried for them. All the dots in Michael’s heart represent family, friends, colleagues and others who were dear to him.
“Millie and Gavin are amazing kids who went through a horrible tragedy. Michael Jackson dedicated his life to supporting children like Millie and Gavin.”
