Wood-colored box, showing a mounted warrior on a rearing horse (the artwork is an adhesive sheet affixed to the box cover) and the price ($10.00).  Incidentally, the image was "inspired by" (*cough*) artwork by Dan Adkins, originally found in Doc Strange comic #167, Apr 1968, on page 11.  That artwork is viewable here (thanks to Jason Williams for the find, and to the Doc Strange discussion forum for the scan!)

Woodgrain striations on the box run horizontally.  Compared to the Third print sticker, this sticker is more centered and has fairly equal whitespace on the borders

Outside cover of Men & Magic shows a mounted warrior (same as box)

Outside covers of all three booklets have a price ($3.50)

Inside covers are white, and do not indicate any printing number

Inside rear covers of booklets 2 and 3 show the printer's imprint -- Graphic Printing of Lake Geneva; booklet 1 doesn't have it

References to Hobbits and Ents are present (copyrighted names of the Tolkien estate; easy check: page 9 of Men & Magic)

Internal typeface is rather rough and difficult to read

1000 copies of this set were printed by Graphic Printing (and hand-assembled by Gygax and friends in his home).  Reportedly took eleven months to sell out.  As evidenced by the additional prints below, there is strong indication that the box, the cover stickers, and the booklets themselves were printed in differing amounts, which led to later "frankensteining" of the various parts

Identical in all respects to the First Print Alpha, except on two points:

Our guess here is that for whatever reason, Volume 3 either had a lower production run, or more likely, a portion of the batch was damaged and discarded.  A new run was commissioned and placed in these (and possibly some of Gamma's) boxes.  The same run was also used in the Second Print, though with "Second Printing -- January 1975" added to the inside

Thanks to Bruce Robertson, Paul Stormberg, and David Witts for help with this info

Wood-colored box, usually found without any sticker on the box.  A contributor who received his in Lake Geneva at the time remembers that the cover sticker was loose inside the box, and had to be manually affixed.  Others who received this set do not remember any sticker at all

Woodgrain striations on the box now run vertically, i.e. this is a "1975" box also used in the Second print, below

Booklets 1 and 2 are identical to the First Print Alpha

Most (all?) of these sets completely lacked a Volume 3 booklet; we'd be interested to hear from those who have this set, to see if a Volume 3 is present and which printing it matches

This print was clearly leftover stock of booklets 1 & 2 after the boxes, stickers, and booklet 3 had run out.  It was primarily given away to TSR employees at the time; David Sutherland, Rob Kuntz, and Tim Kask all had copies.  It may also have been advertised as a "Christmas Special" in the Strategic Review Volume 5 (Dec 1975) for $2 or $4, even though the Fifth Print was well underway by then!

Formerly referred to as the "Pre-Publication Print", which we now believe to be false

Wood-colored box, showing a mounted warrior on a rearing horse (the artwork is an adhesive sheet affixed to the box cover) and the price ($10.00)

Woodgrain striations on the box can run either direction (horizontally or vertically); both versions spotted.  Compared to the First/Second print sticker, this sticker nearly touches the top and bottom of the box, and has more whitespace towards the bottom

Outside covers of all three booklets have a price ($3.50)

References to Hobbits and Ents (see page 9 of Men & Magic) are still present

Internal typeface is still rather rough and difficult to read

Rear inside cover identifies the printer: Patch Press of Beloit, Wisconsin.  Also, a "TSR Hobbies" sticker covers the printed "Tactical Studies Rules"

This print is a hybrid print, with a wood-colored box matched with Fourth print booklets.  Obviously, TSR tossed the first Fourth-print booklets into leftover/overprint Third-print boxes, and called it a day.  Two sets matching this description have so far been spotted, leading us to believe that it was more than a unique occurrence

Thanks to Girard Chandler for help with this info, and for the scan of Booklet 1

Thanks to Matt Farrell, John Huckerby, Luca Lettieri, and Morey Winnett for help with this info, and to John Sohl for the scan

White box, showing a wizard and some orcs (like Fourth and Fifth), but now has a starburst stating "Original Collector's Edition" (this was done to differentiate it from the D&D Basic Set, which had just been released), and the price has been removed

Outside cover of Men & Magic shows a warrior standing with a sword and shield

Outside covers of all three booklets have no price

References to Hobbits and Ents have been changed to Halflings and Treants (see page 9 of Men & Magic), due to copyright conflicts with the Tolkien estate (with the exception of a single leftover reference on pg 6 to Hobbits!).  Furthermore, many other infringements on Tolkien's literary license were excised or changed; notably, references to Balrogs, Nazgul, and even several mentions of Tolkien himself
