On 9 April 2011, Quitely was one of 62 comics creators who appeared at the IGN stage at the Kapow! convention in London to set two Guinness World Records, the "Fastest Production of a Comic Book" and "Most Contributors to a Comic Book". With Guinness officials on hand to monitor their progress, writer Mark Millar began work at 9 AM scripting a 20-page black and white "Superior" comic book, with Quitely and the other artists appearing on stage throughout the day to work on the pencils, inks, and lettering, including Dave Gibbons, John Romita Jr., Jock, Adi Granov, Doug Braithwaite, Ian Churchill, Olivier Coipel, Duncan Fegredo, Simon Furman, David Lafuente, John McCrea, Sean Phillips and Liam Sharp, who all drew a panel each, with regular "Superior" artist Leinil Yu creating the book's front cover. The book was completed in 11 hours, 19 minutes, and 38 seconds, and was published through Icon on 23 November 2011, with all royalties being donated to Yorkhill Children's Foundation.
