Theres no more booze in this speakeasy, at least not any thats drinkable.

The Museum of the American Gangster, which opened its Prohibition-era doors for previews yesterday in lower Manhattan, features a bevy of era-appropriate artifacts. They range from bottles of vintage whiskey proclaiming no government additives to an old Appalachian copper still to classic Tommy guns.

The museum's press tour began in the old Theater 80 space on St. Marks, the entrance to which is a tad more accessible now than during the Prohibition-era. During the earlier time period, drink-seekers had to sneak through an alley into a secret door that took bootleggers, hustlers, thugs and gangsters into the speakeasy.

Guided by museum co-owner and curator Lorcan Otway into the first room, he likened the history of the United States to pendulum swinging between moral certainty and liberty, and included significant events like Samuel Adams objecting to the sugar tax in 1770 and Isaac Hoppers formation of the underground railroad in 1787. Next, Otway demonstrated how the copper still was used in Appalachia to distill whiskey and other liquors.

When gangster Walter Scheib ran it in the 1920s he disregarded the 18th Amendment that banned alcohol. Instead, patrons sipped smuggled liquor around the horseshoe shaped bar, which according Otway, was once the longest bar in the city. Only half of the Philippine mahogany bar is still preserved in the museum. The other half, depending on who in the museum is telling the story, was misplaced or disappeared.
