Well it isn't trash. Someone will pay a for that.
Ok,so I've found a lot more info on it. Thanks everyone. I actually found one for sale,on themissingbite. Is this a reasonably priced site?
I've always thought their prices were high. I looked that up there now that you said that and they want something like $1800 for one of those? That sounds insane to me. I was thinking $100-200, but that's just throwing a number out there. I know that the Picasso box of accessories on eBay brings $300 pretty regularly, it was just a box with OS software, a cassette tape introduction to the Macintosh, and the manuals, and it's always highly sought after. That early Mac stuff does have a following and the Think Different posters are very valuable, so it wouldn't surprise me if your poster is quite valuable (and wouldn't surprise me if it's only worth the $100-200 I thought of at first).
If you're interested in selling it on eBay put up on there as a buy it now with a high price and use the Best Offer option too. Anyone interested can send you offers and you'll get a better feel for what people are willing to pay. I wouldn't risk putting that up as an auction until you know for sure there is a good market that will drive the price towards whatever the real market value is so you don't end up selling it for peanuts.
missingbyte is a bit high - but yeah maybe worth around $300 but at auction could fetch more to someone who really, really wants it and overpay...
That all makes sense. I still have the original apple,poster tube. It's actually spent most of its time,in there. I'd put it back in,and then ship that,in a professional tube. I wish I could have it graded. I'm telling you,it's pretty close to perfect. I actually was hoping to get it appraised,but I have no clue,where to start. Maybe I will just put it up,for sale.
