who is big brother? what does he look like?

The symbol of Oceania and the Party, Big Brother is Oceania's supreme leader, and is omnipresent through telescreen projections, coins, and even large posters warning, "BIG BROTHER IS WATCHING YOU." Big Brother is theoretically one of the original founders of the Party and the Revolution, but Winston assumes he does not exist, will never age, and will never die. He is the mouthpiece of the Party, and the symbol all Party members worship. On posters he appears as a man in his mid-forties, ruggedly handsome, with black hair and a black moustachio.
