A poster advertising a cult UFO conference in Glastonbury was taken down after concerns that a swastika featured on it was causing offence. The symbol is part of the logo for the Raelian movement which believes that humans are descendents of aliens.
Changing World Music, which was selling tickets for the event, removed its display poster after it was defaced.
Event organisers said that although the swastika was adopted by the Nazis, it was originally a symbol of peace.
The Raelian movement was started by a Frenchman who adopted the name Rael and claimed to have learned the alien origins of mankind through an encounter with extraterrestrials.
Its logo features a swastika entwined with a Star of David.
Graham Robertson, who designed the poster, said: "It's a logo that I don't find offensive, it's unusual, but on the poster you can see the picture of Rael."
