Jerry Hall, Philip Treacy, and Brian Kennedy among stars contributing to Incognito art sale

One of more than 3,300 original postcard-size artworks, all priced €65, for sale at Incognito.

Model Jerry Hall, singer Brian Kennedy, and designers Helen Steele and Simone Rocha are among the stars taking part in this year's Incognito art sale.

Ireland's biggest and most unusual online art sale is now in its eighth year and boasts an impressive list of more than 1,200 artists.

What makes the art sale special is that buyers will not know who created their chosen artwork until after the sale has closed.

Incognito is now in its eighth year and boasts more than 1,200 artists.

This year, art enthusiasts can choose from more than 3,300 original postcard-size pieces all priced at €65, no matter who the artist is.

As always, several well-known artists and celebrities are taking part in the initiative, which raises money for the Jack and Jill Foundation.

These include comedian Colin Murphy, fashion designer Heidi Higgins, milliner Philip Treacy, and jewellery designer Chupi Sweetman.

Radio Nova presenters PJ Gallagher and Jim McCabe said they jumped at the chance to support Jack and Jill despite the fact that they may not have the natural artistic talents others possess.

"We have produced a piece of minimalist brilliance for Incognito," the duo shared.

Incognito curator Lucinda Hall said they have never had so many artists taking part and welcomed the chance for new and emerging artists to share their work with a wider audience.

I think for most Incognito buyers, they’re not looking for a particular artist’s work. Rather, they go in for a browse and select something that they have simply fallen in love with.

"Of course, that’s not to say that there aren’t some who have their heart set on unmasking their favourite artist," she said.

Buyers have three weeks to peruse and pick their favourite pieces at www.incognito.ie before the sale goes live on Wednesday, April 24.

Former RTÉ presenter — and former under-14s winner in the Texaco Children's Art Competition — Thelma Mansfield said that while she has been nervous about putting herself out there artistically, she could not say no to taking part when she was asked.

"It took me at little bit of time to build up my confidence," she said. "But I knew I wanted to paint and that it was going to be my future. And I have been a big fan of Jack and Jill from the word go."

Some of the well-known artists taking part include Martin Mooney, Bridget Flinn, Martin Gale, Fergus Martin, and Ruthie Ashenhurst.

Jack and Jill currently supports more than 400 children and their families, such as the Dalys from Leixlip who were at the Incognito launch.

Two-year-old Seán was diagnosed with an extremely rare genetic condition shortly after he was born and required round-the-clock care.

His father Mick said they are delighted to see the number of people taking part in this year's event and helping to raise funds for the vital service provided by the charity.

Knowing Seán is being looked after by experts gives Mick some much-needed peace of mind.

"It is great to have those few hours to focus on other parts of home life, like spending time with Seán’s siblings Laura and Tom, or even to get practical things done, like the groceries, all the time knowing that Seán is safe and under the best possible care," Mick said.

Incognito is Ireland’s biggest online art sale, where buyers have no idea of the artists behind the artworks until after the sale has closed.  

Jack and Jill CEO Deirdre Walsh said the Incognito art sale "quite literally turns art into a currency for care".

From today, art lovers can browse the collection on the Incognito website and create their 'wishlist' before the sale goes live on Wednesday, April 24. Then, it will be a case of going, going, gone.
