The fact that it pops up on other social media doesn't mean much if it is a fake that has gone viral. No point of original publication? I've been unpleasantly surprised by such things in the past and have grown wary. It is entirely possible that this person was standing in front of a real location, holding a placard. The placard itself looks like an image crafted elsewhere (non-realisitic edges) and superimposed by Photoshop over the original placard. The person's left hand looks unnatural in "holding" the placard.
