The sensuous dirty old man (A Signet book)

Signet Paperback Y-4940, 1st Printing Jun 1972. 152 pp. Size MMPB. Binding intact; no loose pages. Covers and pages clean and unmarked EXCEPT no printing on white spine (cover background is red) which may be the way it was published (there's an uncertain appearance of an attempt to make the book appear somewhat salacious); also a couple of minimal bumps on the back cover. Contains numerous illustrations of illustrious and well-known British and American white males, not otherwise appearing to have anything to do with the subject at hand (with the possible exception of Lord Byron, who probably did not live long enough to join the class). The keyword here is that the book "appears" to be about sensuosity (apparently, a branch of sexology, although rarely studied with the same interest as our author gives it) while in fact it is about the humorous subject of sensuous dirty old men, of which class the author, labelled as "Dr. A" and suggested by the publisher to be, perhaps, Dr. Isaac Asimov, denies inclusion.
