Here's hoping this is just what you were looking for--hungarian language books from the mid-1980's to prepare international students wishing to study at a Hungarian university. They start out easy and get much more advanced. The beginning of the books are fairly annotated (which may be useful to you). They're all paperback and the spines are still pretty intact.
I will be leaving town for several weeks on Oct 2, was hoping to gift these in the next couple of days. These are available if this posting is up.
