Basically the title. They sent me the photos, they found them when clearing out parents house. Said books are used but the game is unused
I wouldn't think any of those are particularly valuable, but nice to have sure.
I have a couple of the same first edition d&d books: My dad's from when he ran a campaign for us when I was seven years old. So glad I have 'em still. I run a biweekly campaign with my dad, aunt, uncle, and cousin's husband. (And also play in one run by said cousin's husband, same group.)
