Space Tours - Paint-by-Number Wall MuralSpace Tours Paint by Number Wall Mural Based on the story "Bob the Astronaut", Bob is an astronaut who gives daily tours of the moon. He swears there are no martians, but unfortunately that isn't true and the visitors can see that as they leave the planet in their space ship. Actually the moon has many colorful and very playful martians that love to keep him guessing. Decorating has never been this fun! Check out the matching Chalkboard Mural Blast
