<div>Once a year, the dogs in the paintings in London's National Gallery have an exciting night out. For a few hours, they escape their gilded frames and are free to run up and down the grand staircases, chase each other round the marble halls, and explore the other exhibits. But four of the dogs overindulge and sleepily climb back into the wrong paintings. When the mix-up is discovered, the museum's popularity soars! This playful story, with superb illustrations by Alan Curless and lovely reproductions of National Gallery paintings, provides young children with a charming introduction to fine art. </div>
