Self-published book, the text is strangely printed horizontally, unpaginated, purportedly an alien's account of his experiences with human life in early 1970s Manhattan. The material was meant to be left with the President of the United States "or perhaps with the American Air Force Department, but we were not taken seriously, so we have left our findings with an adjuvant on your planet."
Correction: "The book you are about to read is a documented treatise and by no means is it a book of science fiction", or so the inner front flap warns us.
