Could it be a US publication ? It does not appear in the Bodleian catalogue, either. It would help in a search if the book had an author, or if somewhere in it you could find a place of publication. There may be a publisher's note at the end of the book, if not on the back of the title page.
However, I suspect that this may be one item in a big print-run of an educational title intended as donations from one government to the schools of another country - intended as gift aid of some sort.
