I like the artsy, old-school look of the Penguin Audio Books ad campaign. Although audio books have been around for quite some time now, they are still considered as relatively new technology, especially as they do become more advanced with time. Regardless, the Penguin Audio Books ads take a more vintage approach to their strategy, and are as classic as the books themselves.
Conceived by Malaysia-based ad agency Y&R, the Penguin Audio Books ad campaign parades the characters of some of these classics, including 'The Wizard of Oz' and 'The Jungle Book,' through the canal of your ears. It may be quite a literal interpretation, but it is done so whimsically enough that it still maintains a strong element of imagination.
