Up for sale is a 1985 11-volume Royal Cruise Line Berlitz guidebook set which is housed in a slipcase.  The individual softcover books are rather small, measuring only 5.5" X 4".  There is light edge and corner wear to both the books and slipcase, but no major cosmetic flaws whatsoever.  Please be sure to fully enlarge the provided photos, and feel free to contact me with any questions you may have.
