“CAN’T DECIDE WHICH TEAM TO SUPPORT? WHO CARES — WITH THESE AUCTIONS, EVERYONE’S A WINNER” GOING, GOING… GONE!

Not into the footy? Delight in a different sport this Frieze Week: bidding wars. This year, two of London’s biggest auction houses, Sotheby’s and Christie’s, are engaging in a great big charity play-off. In the Sotheby’s Contemporary Art Day Auction on 15 October, you’ll find works by the likes of Wolfgang Tillmans (head to p28 to read our exclusive chat with the artist), Marlene Dumas, Anish Kapoor and Yinka Shonibare (right) up for grabs to benefit the ICA in honour of the institute’s 75th anniversary. Meanwhile, on 14 October Christie’s is including 23 works, including those by Beauford Delaney and Shirin Neshat, in its Post-War and Contemporary Art Day Sale to support The Istanbul Foundation for Culture and Arts (İKSV) on the 50th anniversary of Turkey’s leading contemporary arts institution. Can’t decide which team to support? Who cares — everyone’s a winner.
