Shakespeare Rainbow Collection Books (Sedbergh LA10)

I a reading Shakesphere's plays in order and have bought the first few of this series which make for more pleasant reading than the Ardent series. Does anyone have any books of the Shakespeare Rainbow Collection which were published between 1950 and 1970 they would like a new home for? I am reading one a month, so the next three years will be taken up with his plays. Even one would be most welcome.
