The Mob Museum celebrates its 14th anniversary by welcoming Nevada residents to experience the Museum for free during its annual celebration. Non-residents get a break, too, with buy-one, get-one general admission.

The museum is home to the most comprehensive collection of artifacts related to the 1929 gangland slaying known as the St. Valentine’s Day Massacre. It was day that transformed law enforcement’s fight against organized crime.

Signature artifacts include the wall from the scene of the crime and one of the Tommy Guns used in the Massacre, as well as original documents, crime scene evidence and more.
