A clipped newspaper article describes a bold undercover operation by Canevari during which he “presented himself as a member of Al Capone’s gang and explained he needed a bomb to exterminate some rival gangsters…[Razzano] Prosperino agreed to sell him a suitable bomb for $250.” The subsequent arrest earned Canevari a promotion. Includes an original glossy 3.75 x 7 full-length mug shot photo showing Prosperino in a suit, bearing a typed notation to the reverse with a physical description and his alleged crime, in part: “Defendant was arrested…for possession and offering for sale a Bomb.” Typed police report describes the course of the trial in which he was acquitted, five pages, 8.5 x 11, dated between January and April 1931. In overall fine condition, with unobtrusive creases to photo and expected wear to documents. Provenance: Eugene Canevari Collection. RR Auction COA.
