Although I am a bibliophile, and I do flip items as a lucrative side hustle, and I'm very familiar with the fact that this book is about a man who is arguably the reason the greatest libraries in our country exist to the extent that they do and provide the wealth of knowledge and culture that they do (still true to this day) - I don't know the first thing about selling used or especially old and rare books, not to mention an autograph being thrown into the equation so some help would be much appreciated in understanding and dissecting what is and is not important of the following facts of this and how to go about determining what it's worth?

-Rosenbaugh a biography -Edwin Wolf II with John F Fleming -First edition -Autographed by Edwin wolf II -Appears to have been personalized as given to somebody known by the author -The world publishing company Cleveland and New York -1936 -Hardcover, canvas cover -Jacket (I'm assuming a later edition to this? Unless it's just extremely well preserved beyond what I would think possible for 1936 to now) designed by Howard t Glasser -Further preserved with a brodart super clear jacket cover which appears to have a serial number (?): 10-409-603

Am I missing anything or did I get anything wrong? Or which parts of the above are most important? Or perhaps irrelevant? Just unfamiliar entirely with the nuances of selling in this niche
