There are two limited editions vying for true first status. The true first was likely published by the Franklin Library as part of their First Edition series. It is leather-bound and limited to an unspecified number of copies. It is not signed, but the spine and copyright page state that it is the first edition. The Franklin Library had a good history of making sure that their first editions were really first.
Then there is a Random House edition limited to 500 copies. The boards are navy blue cloth, and it is issued in a navy blue slipcase, numbered, and signed by the author. Even though it might not be the true first, this one tends to have more value than the Franklin edition because it is signed and numbered.
Random House also produced a "special edition" which states that is has been "prepared for presentation to friends of the author and the publisher". It was issued in a plain glassine jacket and is thought to be a special edition of the trade edition rather than the true first edition.
The first trade edition is undisputed. It was published by Random House and its copyright page states "First Trade Edition" below the Random House number line "98765432". It also states that a "limited edition of this book has been privately printed", which by itself does little clarify which is the true first. Some say it is referring to the Franklin edition because it does not describe the limited edition as signed.
