Although European, American, and Japanese toy manufacturers produced some rather unsophisticated battery-operated toys before World War II, after the war Japanese toy makers took the art to new levels. Several Japanese companies produced thousands of ingenious toys similar to the "Jungle Trio." "Jungle Trio" depicts two monkeys and an elephant playing musical instruments. When powered by two batteries, the toy displays eight different actions. The toy was distributed in the United States by Linemar Toy Co., a division of Louis Marx & Company.
