Do any of the book collectors on here known about the various Ďversionsí of the Wade/Boote classic ?

I have several hard back copies, one has a black spine with white type on the spine and the other hardback has a black spine with red type. Is one a very early version ? I havenít checked for any other differences.

All came direct from Jeremy Wade as he is a mate of mine. But I canít remember why he said the printing was different on some copies.....

Any help much appreciated.
