Precursor to the Kelpies?

I'm sure you've probably seen this pack horse blipped before, he stands 5 metres high, balancing on a plinth in the fairly new Trinity Shopping Centre in Leeds and I love him! Created by Andy Scott - the same guy who recently did 'The Kelpies' - absolutely love his work - what a talented man! I'm not sure if the metal is changing colour slightly over time or it may be my imagination - not quite sure what metal it is actually - regardless, it looks fabulous to my eye and a visit to The Kelpies is high on my list! :)) Andy Scott
