At Washington, D.C.’s Newseum, you can visit convicted Unabomber Ted Kaczynski‘s Montana cabin (pictured above, at left), on extended loan from the feds, in the show “G-Men and Journalists: Top News Stories of the FBI’s First Century.” Having read about the show from his Colorado prison cell, Kaczynski is not amused. “I recently received a page from The Washington Post, June 19, 2008, page A9. This comprises a full-page, full-color advertisement that features my cabin, which is being exhibited publicly at something called a ‘Newseum,’” he wrote to a Court of Appeals judges’ panel in a letter protesting the exhibition of his former dwelling. But has Kaczynski seen the other Unabomber cabin now on view at a major U.S. museum? As we told you last month, the New Museum’s spooky “After Nature” exhibition includes “Unicabine” (2008), artist Robert Kusmirowski‘s replica (pictured above, at right). We asked the New Museum if they’ve received any Colorado-postmarked manifestoes about the piece. “So far, no word from Mr. Kaczynski!” Reports the museum’s communications director, Gabriel Einsohn.
