The sign features an icon of a flying saucer above the text. The ground around these elements is uneven and textured, suggesting an extraterrestrial landscape.On the right side of the image, three animate figures are shown ascending a hill towards the spacecraft. These figures are stylized and non-human, possessing large, circular torsos and three protruding eyes on stalk-like projections from the top of their heads.
