Typical Black Hand tactics involved sending a letter to a victim threatening bodily harm, kidnapping, arson, or murder. The letter demanded a specified amount of money to be delivered to a specific place. It was decorated with threatening symbols such as a smoking gun, hangman's noose, skull, or knife dripping with blood or piercing a human heart, and was frequently signed with a hand, "held up in the universal gesture of warning", imprinted or drawn in thick black ink.
