This is a drawing in black and white. It shows three space people and some space things. The first space person is busy talking. They are looking at a book and pointing. The second and third space people are looking surprised. They are pointing at something flying. The flying thing looks like a ship with a round top and a light. It''s floating above some flying rocks. There is also a stand with signs on it. The signs have shapes like arrows and crosses. There are wavy lines around, like it''s a bit windy. Everything looks like it''s happening on another planet. The ground and plants do not look like Earth.
