Communiqué issued on April 21, 1937 by the Palestinian Arab Information Office in Cairo, whose president is Mohamed Ali Eltaher, about the situation of Palestinian political detainees imprisoned in the Mazraa detention camp near Acco.
It is interesting to note that the cover page of this communiqué is actually the reverse side of a book entitled "Palestine Land of Martyrs" that Eltaher was going to publish, but all its originals and printing plates were seized by Egyptian authorities working on behalf of the British.
