No, I don’t think it is photoshopped, I was wondering how many regular Cubans were able to see it; it obviously isn’t made to be there long. The picture is unusual in that this is a big event and there’s no crowd in it. Not a soul; it looks like the photographer wanted it to look abandoned.
I think I read that it was put up about a week before the Pope’s arrival, so I would think many people saw & certainly heard about it.
Since it was right in the area where the Pope was going to hold mass, they may have prevented people from gathering in the area prior to his arrival, for security reasons.
