Naga Drum and the obscurity of the Naga presence on the internet

I am trying to find what a Naga drum looks like, but I can't find any image even on google. Isn't that amazing? Sometimes its annoying that Naga culture is so obscure, that even to a person who knows where to look and where I can find, I still find it so hard to track anything about Nagas down. Imagine how much impossible it will be for someone who has no idea about us and is trying to find out any information from scratch.

Where does one look? Where do you start?
