A first glimpse of Aurora, the world's largest polar bear - big picture

The sculptors have been working from design specs and artist's impressions by Christopher Kelly as well as from various photographs of polar bears and moodboard imagery of Shackleton's polar expedition, ships, ragging and wrote iron metal-work. The three-tonne marionette bear will be operated from the inside by a team of 15 puppeteers, including artists from West End blockbuster War Horse.
