Incredibly, as the investigative team at Muckrock discover, the presence of a brochure for the creepy-looking Buffalo Bill Wax Museum among the cache of declassified material from the Central Intelligence Agency has an even more bizarre reason for its inclusion. Not just hoarders of ephemera, they kept the historic document of the exhibition as it was decades ago in hopes of teasing out evidence of not just extra-sensory perception but also time-travelling abilities. What exactly was behind the choice of this chance culture touchstone (or rather, shibboleth) is unclear.
