The wishlist name can't be left blank


TAG Fine Arts is a global contemporary art dealer and publisher based in Islington, London.  Founded in 2006 by Hobby Limon and Diana Ewer, we’ve been championing the work of emerging and mid-career artists who have graduated from the UK’s finest art colleges ever since.

The gallery quickly became a household name after a series of successful cartographic publishing projects that were acquired by corporate buyers, museums and major art donors including Blackrock, Deutsche Bank, David Roberts Art Foundation, Fidelity International, Hiscox, British Library, British Museum, Government Art Collection, Houses of Parliament Collection, London Transport Museum, and V&A Museum. 

Today the scope of our artists reflects TAG’s dynamic and global collector base that has grown exponentially over the years. We like to think of our clients as family. We love nothing more than catching up at art fairs and exhibitions in the UK and abroad, regularly showcasing artwork in London, Hong Kong, Singapore and the United States.

Close relationships with institutions and companies such as Bordier & Cie Singapore, Bank of America, Bupa, Clifford Chance, Credit Suisse, G.O.S.H National Health (Trust UK), Linklaters, Morley Fund Management, Norton Rose, Paul Smith, Rolex, Sainsbury plc, Sony, Standard Chartered Bank, Wheelock Properties Singapore, and Unilever underpin the gallery’s continued success.  At TAG we continue to find innovative ways to present our artists’ work to new audiences by hosting major exhibitions abroad - a recent collaboration “Ewan David Eason Mappa Mundi” show for The America’s Cup with The Hamilton Princess Hotel Art Collection in Bermuda is a great example of what we do best.

But home is where the heart is and we look forward to welcoming you to TAG Fine Arts’s North London space where we would be delighted to assist you in your search for the perfect piece of art for your walls.

TAG Fine Arts is an accredited member of LAPADA, the UK’s Association of Art & Antique Dealers.
