Just in time for Valentine’s Day comes the opening of the Mob Museum in Las Vegas, a $42 million survey of the American gangster.

In an ironic twist, which was not lost on the museum’s designers, Feb. 14 marks the 83rd anniversary of the Valentine’s Day Massacre in Chicago, where members of George "Bugs" Moran’s gang were murdered by Al Capone’s rival thugs posing as police officers.

The museum is housed in 17,000 square feet of exhibit space in a former post office and courthouse in downtown Vegas.
