Once dangerous sea monsters, now friendly giants: we can't seem to agree on what whales represent to us. Measuring 33 metres long, the blue whale is the largest animal to have ever existed on earth. Not only their size, however, but also their human-like song never ceases to amaze; they use their voices with great aptitude to communicate with each other under the water. With a whale poster on your wall, you'll also nod towards the fascinating underwater ecosystem which whales inhabit and maintain. All hail wonderful whale art!
