This is a drawing in black and white. It shows three aliens near a big flying saucer. The saucer is above them, very large, and has windows and a ladder coming down to the ground. The aliens are walking on a rough path. One alien is behind and looks surprised. Two aliens in front are moving towards the saucer. One has a suitcase. There is a sign next to the path that says "EARTH" with an arrow pointing towards the saucer. The background is simple and empty.
