The United Nations Educational, Scientific, and Cultural Organization has announced through its Paris Office that a new comprehensive Unesco coupon has been issued which can be used for the purchase of publications, films, and scientific material, and which will replace the old ‘book’, ‘film’, and ‘scientific materiel’ coupons.
