This is a review of the softback booklet version only. I decided to save the hardback one until the RPG set including it is ready!
Latest in the line of reproduction Miskatonic University Press’ Monographs from the early 20th century by the HPLHS, this booklet enjoys the usual formatting for that series, including images of the original document on glossy paper, two as fold-outs, and two, including the cover photo - in colour. The illustrated, expert-written texts are all we’ve come to expect from others in this Monograph collection, here with those experts sometimes tying themselves metaphorically in knots in trying to explain the inexplicable. Rare use of contractions, such as “it’s” for “it is”, jar occasionally, compared with texts from the historical 1920s and 1930s, but these are minor distractions overall, in another beautifully-produced work of its kind. Ah, those hidden messages are calling, not least thanks to the mystical time-travelling nature of the book, no doubt a result of the action of the text’s extracts contained within (see the interior copyright date, if confused!).
