A slightly mysterious book about a blowhard

Several databases include mention of a book titled “The death of Booth: Affidavit Dec. 1, 1904 in pension claim of Wm. H. Collyer, a blowhard.” Apparently it is brief—just three pages long.

We have been unable to find a copy of that book. If you have a copy, we would enjoy seeing an image of the cover and the insides.
