Founded in 1994, The Blue and Gray Education Society considers itself to be "America’s Premier Civil War Education Group." As a 501(c)(3) non-profit, it describes its mission as being "dedicated to assisting members in pursuing their intellectual interests and achieving their legacy by revealing our past for our future through the understanding of the War between the States, by interpreting and preserving its battlefields, conducting high quality seminars, promoting and publishing scholarly research and by facilitating worthwhile education endeavors."
To assist in achieving its end, the Society has, to date, partnered with three well-known authors to create leather-bound limited editions of the author's latest work. These "special leather bound editions are National Geographic authorized deluxe editions" whose purpose is to raise funds for preservation and education. They are only available through The Blue And Gray Education Society.
This series includes Shiloh 1862 by Winston Groom, Fields of Honor by Ed Bearss, and Receding Tide: Vicksburg and Gettysburg by Ed Bearss with Parker Hills. Each volume is $43.
No word at the website as to whether or not these editions are signed and/or numbered by the authors. If they were, I think it's safe to say that that fact would be highly touted. Update to follow. UPDATE Sept 3
