The book is in VG condition with the following faults
Light rubbing to the cover boards.
Puzzle completed.
The book is otherwise clean and bright, unclipped and not marked.
8.5 out of 10
I sell mostly second hand books and I try to convey overall condition by rating out of 10. New would be 10, whilst anything over 9 would be collectible in that the book would be lightly read, and with no damage or wear. An 8 rating would be a decent copy, appropriate for its age.
Once it gets a 7 rating, then there will be faults that you should consider carefully. 6 or lower are generally reading copies or collection fillers that are offered because of their rarity or interest. Again, check the faults carefully.
