Zoom way in. So you can only see a couple of words. Compare the top, in black, sign, to the bottom, in red, sign. Totally different, artifact-wise. See all the pink smearing on the bottom portion, with no smearing on the top? The top “may” be legit, but the bottom is not. Now scroll down the sign’s handle. Notice that the girl behind the sign has a small portion of her hair in front of the handle. Scroll down further to the area of the handle right above the guy’s hand. I still say Photoshopped, although I wouldn’t doubt the sentiments expressed.
See all the pink smearing in the white stripes of the flag behind the girl?
"...of her hair in front of the handle."
That's a reach. The highlight running up the handle is consistent. I'd go with uneven edge on the stick.
I can't see the point in faking something that actually is happening.
