Ron Cobb created this logo by combing the letter “e” and the letter “o”; to combine earth and the environment with wholeness and unity. It was first published in 1969, a year before the first Earth Day. It was later put on a green version of the American flag and called the Ecology Flag.
Ron Cobb was born in Los Angeles in 1937. He drew cartoons in the 1960s and 70s. He drew concept designs for Dark Star, Alien, Close Encounters of the Third Kind, Real Genius, Back to the Future, Aliens, The Abyss, Total Recall, True Lies, The 6th Day, Cats and Dogs, Firefly and Southland Tales.
