English: First published by Straight Arrow Press. Cover design by Thomas W. Benton (source: tomwbenton.com). Benton was not credited on the original dust jacket; the credit "with Illustrations by Ralph Steadman" refers to the interior contents of the book itself, not the cover.

English: No permission is required because the dust jacket was first published prior to 1978 without a valid copyright notice. Fear and Loathing on the Campaign Trail '72 was first published in book form in 1973. The book itself had a valid notice on the copyright page, and much of its contents were previously published in Rolling Stone magazine, so its contents remain copyrighted. However, the first-edition dust jacket did not carry a separate copyright notice. According to The Compendium of U.S. Copyright Office Practices: Chapter 2200, § 2207.1(C) at p. 15:

A notice of copyright on the dust jacket of a book is not an acceptable notice for the book, because the dust jacket is not permanently attached to the book. Likewise, a notice appearing in a book is not an acceptable notice for the dust jacket or any material appearing on that dust jacket, even if the book refers to the jacket or material appearing on the jacket.

Keep in mind that the pre-1989 requirements for copyright notice were highly formalistic and, other than a few enumerated exceptions, required these three elements:

1. "The symbol © or the word 'Copyright' or the abbreviation 'Copr.' or an acceptable variant such as "(c)";
2. "The year of first publication for the work"; and
3. "The name of the copyright owner, or an abbreviation by which the name can be recognized, or a generally known alternative designation of the owner."

If just one of these elements is omitted, the work is deemed to be published without notice and is not eligible for copyright protection. Neither the year "1973" nor a copyright symbol (or any acceptable variant) appear anywhere on the dust jacket. The mere identification of the publisher and author do not meet these requirements. The lack of notice on the dust jacket can be verified by examining the full-jacket scan at this iCollector listing or this WorthPoint listing.
