There could be only one picture of the day: Sir Peter Blake at the unveiling of his mural "Appearing at the Albert Hall". The triptych, which is in the hall's foyer, features more than 400 artists in Sgt Pepper album cover style. It's an irresistible game trying to see how many you can name. A version of the photograph above makes the front of the Guardian - with a great heading - and the Times also uses the central panel on page 3, with a little quiz to set readers searching for five faces. The Independent runs a slightly wider shot across a gutter (which doesn't help), but the picture is strangely absent from the Telegraph, Express and Mail - watch out for a whistles-and-bells catch-up spread from the Mail later in the week. The Mirror and the Sun do best. Both show all three panels across a full spread. The Mirror (above right) gives a key and names everyone, the Sun directs readers to its website for the list. That's what everyone should have done.
