This early article about the new movie discusses why the four films to date have failed to do justice to the book. I've seen the last two versions and all I can say is good luck to Baz and company (Daisy's hair still blonde).
The first edition (New York: Charles Scribner's Sons, 1925) is one of the highlights, if not the highest, of modern first edition collecting. And there have been interesting editions since. One of the most interesting is a five part serialization in 1926 in The Famous Story Magazine (April, Volume III, No. 1 through August, Volume IV, No. 2). Twenty years later the first mass market version was published by Bantam Books. Later printings have an added dust jacket with Ladd on the cover.
