Flag "of Palestine" in Nouveau Petit Larousse Illustré, 1924.  Appears to combine the Star of David with the gold-and-white colors of the old crusader kingdom of Jerusalem.  (See also FOTW page http://www.crwflags.com/fotw/flags/il%7Dz1924.html .)  To see the actual flag of the British Mandate territory of Palestine (insofar as this was not simply the Union Jack), go to File:Palestine-Mandate-Ensign-1927-1948.svg.
