So, I recently won a copy of U&WA @
** expired/removed eBay auction ** (along with a 2nd
GH from the same seller; neither is in particularly wonderful condition, but that's OK

) but I find that without the other books on hand, it's not very easy for me to tell what printing that book is.
Am I just missing the obvious clues @
Original D&D Set? If not, are there any good telltales that would clearly ID the printing of the book without being able to refer to another book or the box?
