Over a year ago I purchased this:

It’s the original AD&D Forgotten Realms box set from 1987. It’s in great condition, and all the elements are included:

I didn’t open it until the other day, and imagine my surprise when I saw this on the title page of the main book:

It’s autographed! Here’s a close up of Jeff Grubb and Ed Greenwood’s:

With a bit of effort I was able to find images of both online and these certainly look genuine.

I wonder where and when they signed this 27-year-old box set? And I wonder if the seller who sold this to me for under $20 realizes it’s easily worth up to $10k due to the signatures 😉
