This beautiful scan of a vintage Victorian greeting card shows a man bringing the moon a plate of cheese.
I really like this strange image of a cartoon moon face, he looks a bit crazy really, but I like it.
Blue moon animation with a twinkling star.
(Trivia: a moon is called a blue moon when it's the second one in a month, which is rare and where the term "Once in a blue moon" comes from.)
This is one of my favorites, the moon looks so soft and friendly, or maybe curious as it looks down from among the stars and clouds.
Here's a rather dramatic image of tall skyscrapers of a city skyline silhouetted against a very big, glowing full moon.
