Great moments in spin
The plaque marks the spot where an eager reporter from The New York Times, Herbert Matthews, interviewed a thirtysomething Cuban lawyer turned guerrilla leader, Fidel Castro.
The interview ensured Castro enormous favourable coverage not just in the US media but inside Cuba, too, with Matthews describing the rebel commander as an "educated, dedicated fanatic" and "a man of ideals, of courage and of remarkable qualities of leadership."
It was the beginning of the Castro "legend".
In fact, however, it was nothing but good, old fashioned PR, as the dictator himself admitted a few years later.
Much to Matthews' embarrassment, Castro bragged that he only had 18 men at the time, but made them pass in front of the obviously not very inquisitive reporter several times to exaggerate his fighting force and impress the Americans.
Matthews, who died in 1977, fell for it. Hook, line and sinker.
Sadly, he wasn't the last Western reporter to fall for the hype, either ...
