Few things take us back in time more effectively than the advertising art of decades gone by, and a collection of images recently featured at Flavorwire.com we found utterly charming.

Every child loves a visit to the zoo, and we’re willing to bet that every visitor to Cladrite Radio will be glad that we shared Flavorwire’s collection of vintage zoo posters from all over the world. And we do mean all over the world, from the Bronx to to London, Antwerp, Tel-Aviv, Munich and Berlin.

Not all of the thirty posters originate from the first half of the 20th century—our focus here at Cladrite Radio—but many of them do, and all are well worth savoring.

Enjoy the examples below, then enjoy the entire collection.
