Ron Cobb created an ecology symbol, which was later adopted as the Earth Day symbol. It was published on 7 November 1969, in the
Los Angeles Free Press and then it was placed in the public domain. The symbol was a combination of the letters "E" and "O" taken from
the words "Environment" and "Organism", respectively. Look magazine incorporated the symbol into a flag in their 21 April 1970 issue.
The flag was patterned after the flag of the United States, and had thirteen alternating green-and-white stripes. Its canton was green
with the ecology symbol being where the stars would be in the United States flag.
