How do I upload the image? I have the photo on my computer but I can't work out how to do it. I joined imageshack and got the link. I tried to do what it said but it just didn't work.
If you uploaded it onto imageshack, just copy the link that might be called "direct link to image" or something like that. Or any of the thumbnails. We'll work it out and eventually will be able to see the image, don't worry for that.
I know you won't want to hear this, but signed items aren't necessarily going to bring a higher price, especially for items that aren't terribly rare. You might be lucky to get $50 for this in today's market, given the condition looks a bit rough (or is that just the photo?). But you never know your luck.
