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