Well, the UFP Flag didn’t end up being flown for very long. We’re now flying the Earth Day flag that was designed by John McConnell, founder of Earth Day in 1969. This version of the flag features the famous photograph of the Earth that was taken from the Apollo 17 spacecraft. The original version was screen printed; but both were official Earth Day promotional items used to advertise the occasion.
The flag I’d originally wanted to fly for Earth Day is the “Flag of the Earth,” (shown below) that was designed by James W. Cadel. It shows a stylized collection of the Earth, Moon and the sun. It flies at Observatories and SETI installations world wide.
