There are still signs of WWII around Miami Beach. Here's one of them - The Viscay Hotel located at 960 Collins Avenue, built in 1942.
There is a “V” displayed on the terrazzo floor at the front entrance. Above the “V” are three dots and a dash, which is Morse code.
During WWII, the Allies wanted a piece to use in their propaganda to support the war effort, and Beethoven's 5th Symphony stood out because, in addition to being awesome, that famous opening motif, repeated throughout, (Da Da Da DUMMMMM...) if you put it in Morse code (short short short long) is the letter "V".
