From the Huffington Post of December 31

Outside of cropping the picture above and possibly tweaking the contrast, photographer Paul Needham assured The Huffington Post that the image is neither doctored nor edited in any way.
Needham is the co-founder of SimpaNetworks, a company that helps farmers and small shops in rural India install and use solar power systems. He said he stumbled across the scene while driving through Mumbai to meet with some investors.
He said he was inspired to take the photo because of the jarring juxtaposition of the Trump billboard and the poverty and homelessness down below, and that the text on the billboard struck him as particularly naive and offensive.
“I saw Trump towering over the homeless, the children sleeping on cardboard on the street, and I was reminded of the ways in which our [an] economic system can be painfully exclusive and unfair.” Paul Needham
