If this poster is real it's worth way over £200.
I've never seen quad artwork before for this movie.
The other quad is pretty rare but well known amonsgt war movie collectors:

Perhaps Terry at Quadbod could chip in when he's back from his travels. Terry, have you ever seen the quad with the waves?
Harry -- The Cruel Sea is a great ww2 war movie about the battle between the U boats and the Navy. Based on a book by Nicholas Monserrat, it reeks of authenticity and you get the feeling that this is what it was really like...this was the kind of black and white movie that they used to show on TV during those wet sunday afternoons in 70s.
