'Pamela Allen should be declared a 'national treasure'. It is almost forty years since her first picture book Mr Archimides' Bath was published to much acclaim. Since then very few Australian and New Zealand children would not have experienced the delight of her picture books. The magic continues, as invitingly and as assured as ever with book number forty-eight: A Bag and A Bird. Just a glance at it's cover with that characteristic high definition pen and wash art sharply focused against white space would have young familiar readers enthusiastically identify it as a Pamela Allen book.'
