Well, I'm not good at pricing stuff for eBay, since I have no idea what is normal for stuff like that. I've never gone on eBay myself, so I wouldn't know.
But it looks like one of those little books that give tips on several game boy games instead of a comic. I remember getting a book one time telling about how to get past tough parts in SNES games. It had a picture of some clairevoyant (fortune telling person) on it.
Anyway, I bet that gameboy thing was another one of those book things at that time, which was back in something like 1992-1993.
Lots of memories, like how it told how to get past the Sunsoft difficulty on Lemmings. I'd say $50-$70. And if it's one of those ultra rare comics like the Super Mario Adventure comics, I'd bring up the price even higher.
I have a feeling that I ''under-guessed.''
Since I have no idea what to price these things, I want to hear other people's opinions on the matter.
