The first notable charity trail was the Wild Dolphins initiative in 2014.
A total of 50 uniquely designed sculptures were placed at locations across the Granite City.
The trailblazing scheme raised £531,000 for ARCHIE Foundation and for Whale and Dolphin Conservation.
They are now permanently situated across the city, including Spiderdolphin – painted in the superhero’s red and blue iconic colours – which has pride of place in Albyn School.
The original Oor Wullie trail was launched in the summer of 2016 in Dundee, the birthplace of the beloved character.
It raised more than £883,000 for the Archie Foundation and featured 55 statues of Wullie in various guises, painted by local artists.
The money raised went towards the Tayside Children’s Hospital appeal, which was aiming to raise £2 million for a new twin operating theatre suite.
Inspired by the success of these events, Friends of Anchor launched its 20for20 campaign last year.
Marking its 20th anniversary, the charity enlisted the help of local artists to paint 20 anchor sculptures which were on display throughout 2017.
At the end of the year, 14 of them went under the hammer to raise funds for the charity’s £1 million Dream Big appeal to recruit a world-class cancer research team.
More than £160,000 was contributed towards the campaign.
And last week, Maggie’s Penguin Parade, held at the newly-opened V&A Dundee, raised £540,000 – enough to fund the charity’s Tayside centre for a full year.
