'Drishti Bommai' AKA 'Ward of the Evil Eye’ is kept in front of the buildings while in construction.
These Dolls are considered to be the remover of `evil eyes'.
The simple one would be, drawn face of devil on a pumpkin or a man created with straws and face drawn with charcoal on a white paint pot.

Recently I came across an entirely different ward.. posting here for your view.
Probably the owner of building thought that, there are pretty big evils in the city and the ward should be big enough to frighten them up. ha ha ha. LOL.
