Hi Jeremy,

Excellent detective work! Many Thanks indeed for that. That certainly makes a lot of sense and explains why I had not come across one before.

I actually acquired it from a UK Seller. Maybe it was someone working in Harpercollins at the time who decided to keep one for themselves. In any case, it is great to know the background to the item. I am very grateful for your time spent in researching this. I could not find anything at all online about it myself.

Many Thanks Again!!!
