In Israel in the 1950s and early 1960s there was a thriving industry of locally produced Tarzan adventures published weekly in 24-page brochures by several competing publishing houses, none of which worked with the Burroughs estate. The stories featured Tarzan in contemporary Africa. A popular theme being his fighting against the Mau Mau in 1950s Kenya and single-handedly crushing their revolt several times over. He also fought a great variety of monsters, vampires and invaders from outer space infesting the African jungles and discovered several more lost cities and cultures in addition to the ones depicted in the Burroughs canon. Some brochures had him meet with Israelis and take Israel's side against her Arab enemies, especially Gamal Abdel Nasser's Egypt.
