In 1988, it was discovered that an envelope had been seized by the United States Post Office Department in 1917 because of its "subversive potential". The envelope, with a photo affixed, captioned "Joe Hill murdered by the capitalist class, Nov. 19, 1915," as well as its contents, was deposited at the National Archives. A story appeared in the United Auto Workers' magazine Solidarity and a small item followed it in The New Yorker magazine. Members of the IWW in Chicago quickly laid claim to the contents of the envelope.
After some negotiations, the last of Hill's ashes (but not the envelope that contained them) was turned over to the IWW in 1988. The weekly In These Times ran notice of the ashes and invited readers to suggest what should be done with them. Suggestions varied from enshrining them at the AFL–CIO headquarters in Washington, DC to Abbie Hoffman's suggestion that they be eaten by today's "Joe Hills" like Billy Bragg and Michelle Shocked. Bragg did indeed swallow a small bit of the ashes with some Union beer to wash it down, and for a time carried Shocked's share for the eventual completion of Hoffman's last prank. Bragg has since given Shocked's share to Otis Gibbs. The majority of the ashes were cast to the wind in the US, Canada, Sweden, Australia, and Nicaragua. The ashes sent to Sweden were only partly cast to the wind. The main part was interred in the wall of a union office in Landskrona, a minor city in the south of the country, with a plaque commemorating Hill. That room is now the reading room of the local city library.
