I asked whether you knew where this sculpture of an Elephant can be seen. The answer is between the up and down escalators on the Jubilee line concourse at Waterloo station.
The elephant is the work of Kendra Haste, who specialises in animal sculpture. London Underground acquired the sculpture in the late 1990’s and Waterloo Station has been it’s home ever since. There are reasons as to why there an Elephant at Waterloo, and Londonist has the full story in Why Is There An Elephant In Waterloo Station?
