Nope it's not fake.
A 41-storey building in the US city of Chicago has shown a huge beacon of support for Mayo.
With All-Ireland day looming, Mayo are the only team left to stop the Dubs on their march to 6 titles in a row.
But it's become obvious that their support goes far beyond the boundaries of the county, or even the country.
The huge Prudential Building in the Windy City, which is a landmark itself, has been up with the famous 'Mayo for Sam' catchphrase.
The message its spelled out using the room lights on different floors, meaning you can't miss it.
There has always been a strong link between US cities like Chicago and the Irish, but something about this latest gesture just warms the depths of our patriotic hearts.
And maybe, just maybe, the "Green and Red of Mayo" will be echoing through the streets on both sides of the ocean this weekend.
