The Museum of the American Gangster
Update - it appears that this museum is closed. They were having problems with the landlord
There’s a museum for everything you can imagine in New York City! I haven’t been to The Museum of the American Gangster yet. They do have a website, but unfortunately it has very little information on it. Below is information about it quoted from Wikipedia.
“The Museum of the American Gangster is a two-room museum located at 80 St. Mark's Place in the East Village, Manhattan New York City. Opened in 2010, it is located upstairs from a former speakeasy in a neighborhood once frequented by Al Capone, Lucky Luciano, and John Gotti. Its Exhibition of the American Gangster was "founded to preserve newspapers, photographs and other original documents from the Prohibition Era". The museum's collection of memorabilia of organized crime in America includes John Dillinger's death masks, bullets from the Saint Valentine's Day massacre investigation, and a bullet from the shooting of Pretty Boy Floyd. The exhibit is currently open. It is also possible to tour the old speakeasy.”
