I do not know about a specific instance of someone holding up a sign like the one in the photo I linked to, but I also sincerely doubt anyone in their right mind would attempt such a thing.
The closest recent example I can find is someone painting the names of the Castro brothers on a pair of pigs and being thrown in prison for it (in 2015):
Far worse things happened during the early days of the revolution. I was going to link them but I changed my mind because I don't want to weaken my point. Freedom of speech is far stronger in a place like the US than in a place like Castro's Cuba.
