An ash I know, Yggdrasil its name. With water white is the great tree wet; thence come the dews that fall in the dales. Green by Urth's well does it ever grow.
I have Escape From Colditz first edition by Parker Games 1973. It is signed on the rear of the box by Pat Reid the designer and Escape Officer at Colditz, how much is it worth

But the signature makes this a question that I doubt could be answered. You'd have to auction it to find out.
