Brightly coloured elephants in Central London

There I was wondering down the Cromwell Road to the Marriot in Kensington today and I saw a brightly coloured elephant. 
It was not a hallucination.
I wasn’t too shocked as I had heard there were many around London.  
No it isn’t the time of year…………
There are over 250 of them at various locations as part of a campaign to help endangered Asian elephants. Each one decorated by an artist or famous person.
If you are feeling flush, they are going to be auctioned for charity.
