Perhaps a piece of plexi-glass inserted where the heart shape is painted translucent red. Bike painted black and a 4 leaf clover and something symbolizing bootlegging and, VIOLA! St. Valentine's Day Massacre Bike.
The Saint Valentine's Day Massacre is the name given to the 1929 murder of six mob associates and a mechanic of the North SideIrish gang led by Bugs Moran during the Prohibition Era. It resulted from the struggle — between the Irish American gang and the South SideItalian gang led by Al Capone — to take control of organized crime in Chicago. Former members of the Egan's Rats gang were also suspected of having played a significant role in the incident, assisting Capone.
