Yep - it is the type of item which has zero value to me, I only have it because I'm a packrat and rarely toss stuff out.
But my experience is - people collect the oddest stuff.
I suspect if I still had my copy from 81 or 82 (whichever was the first year they printed them) it might be worth more to someone, but way back when I got this one I probably tossed the original (I know I had an older one because I recall a mistake in a friends listing that isn't in the '86 one).
