One of the authors of this book, Alan Whanger, does mention in another publication that “the sticky tape slides were sealed in her [Mrs. Frei’s] presence for transportation back to the United States” (Whanger, “Pollens on the Shroud: A Study in Deception,” Shroud News 97 [1996], pp. 11–18). But I wonder what is meant by “sealed,” and I also wonder why there is no mention of what happened to all of the other pollen evidence that Frei reportedly examined.
