Naw, that's real. First, it's not just a font, it's got some pattern to it, like it's woven, big time pain in the ass to recreate. Also, in the two photos look at the carpet in relation to the wall, it doesn't move even though the angle of the camera does, making it a fixed object in space, another huge pain in the ass. Then, since the camera moves, the angle of the letters changes, while not the hardest thing in the world, it's spot on. Also, the McDonalds French FREEDOM Fry box underneath the Tower One is in the same relative space, as are the cracks in the pavement. So you're talking a decent amount of work for a slight that isn't that powerful.
It's not that shocking, you can buy anything with the flag on it anymore, hell I can remember welcome mats with the flag on it since the 70's.
