Nice reference pictures for Heffalumps.

BBC story of a rest and recuperation camp for working elephants.

Some great pictures showing the characteristiic features of the asian elephant.
Notably:
   Rather darker skin tone tan you'd expect form Dumbo and Babar stories - almosta carcoal grey.
   Characteristic freckles on nose bridge, trunk and edges of ears.
