Port did not have a black and white jumper before Collingwood. Go back to one of my previous posts where I posted a YouTube link, showing the history of Ports guenseys. They even used the Collingwood guernseys for a few years..It's an amazing discussion,
From what I have read Port had a black and white jumper 20 years before we did.
But to counter that Port joined the AFL as a new Port Adelaide and has no connection to it's past?
Others can counter Collingwood was called Britannia Football Club.
