This stamp of Aladdin’s Cave was issued in 1967 in Iraq. A few other middle Eastern countries issued Arabian Nights theme stamps in that year. The ones that I know of include Ras al Khaima, Fujeira, and Ajman. This Iraqi stamp provides a clue as to a possible reason. Besides being the Canadian centennial (and I doubt that they were commemorating that) 1967 was also International Tourist Year.
