I've a still sealed copy of this, complete with the poster, if anyone's interested. £10.00 and it's yours. Free postage in UK, would have to find out how much to anywhere else.
The American Slang has been opened (as I got both black and green and it wasn't evident which was which), it has not been played. Looking for £20.00 for that one. Again, will ship free in the UK.
Message me if you're interested.
