During the 1950s, Chester Zoo began to invest more in marketing to generate more visitors following the war. The slogan ‘Always Building’ was created and the logo was a beaver to reflect the pace of post-war reconstruction. New animal houses and enclosures were built, including a giraffe house, a camel house, zebra house, an aviary for macaws and cockatoos.This is believed to be the first TV advert for Chester Zoo.
