One of my prize purchases in the Flea Market (and I had a bunch) was a collection of Wargamer's Digest magazines that I picked up for only $15. These can normally be had as singles for $1 each so figure I got them for about half price (or maybe a little better - haven't done a total count yet.) The set included issue 1 (yay!) but also issue 7 - May 1974.
The main significance of this issue for me, is that it includes the following article by the great EGG himself!
Here we have it - a contemporary description of the dawn of D&D - not one recounted years later.
