Old Mafia file going on NYC auction block

The New York Post reports:

It was an unlikely — and coveted — find: a thick United States government file discovered on the backseat of a New York City taxi, its pages containing mug shots, criminal associates and favorite hangouts of over 800 Mafia members during the 1950s and early 1960s. Such notorious figures as Carlo "Don Carlo" Gambino, Meyer Lansky and Salvatore "Lucky Luciano" Lucania each had their own entries.
Nearly 20 years after it was found inside the yellow cab by a passenger, the 3-inch thick, three-ring binder stamped "Mafia" and "United States Treasury Department Bureau of Narcotics" is being offered for sale at Bonhams New York on Wednesday. Its pre-sale estimate is $10,000 to $15,000.
