In the second-greatest art auction of the summer (following the one for a pair of Nick Cave’s socks), Art on a Postcard is back for 2020. Basically, a lot of world-famous artists are invited to contribute a postcard-sized original work, then you get to bid on them online (starting at just £50). This year, some of the big names involved include the Chapman Brothers, Julian Opie, Oh de Laval, Lothar Goetz and Remi Rough. Oh, and Boy George is chipping one in too. Mr O’Dowd has taken up the brush, and even enjoyed a sellout show last year in Monaco (posh!).
