Day 7: First D&D product you ever bought. Do you still have it?
Wow, my memory really isn't good enough for these questions.
I believe it was the Holmes D&D boxed set. I still have it all including the dice. It is severely banged up; it is less a box and more a bunch of flat sheets of cardboard holding the paper in one place. I am the sort of person who believes in using things and not putting them away "for safekeeping". I figure the more something is banged up, the more it shows the love. Of course, I haven't played 1E since 2E came out, but I'm still glad I still have the box set.
