In the exhibition Ape to Zip this work was used for the letter M and was displayed with the following label:
This giant gold heart is also an upside-down map of the world, with New Zealand at the top! It has all been made from chocolate wrapping paper.
Who thinks the artist likes chocolate?
And here's history: a heart-shaped world map was first thought of exactly 500 years ago by a really inventive man called Johann Werner.
