I was at a Flea Market with my parents, a week ago. I saw this on the table, and ran over to see it. I had no cash, so I had to turn it down. Luckily, my Parents were nice enough to sneak back out later, and buy it for me. So, I received it today. Like I said, it looks completely unissued. I don't know much about it, so I need help placing a value on it, and giving me a bit more history about it.
