From our point of view on Earth, there are three bodies that have a crescent when we view them: Mercury, Venus and Luna. Of course from a different vantage point (such as a space probe) every planet and moon will show a dark side.
sorry, I didn't write that very well. I meant to say, print out the Venus picture from the Drugde site and turn it upside down. Compare with the planet in the montage. The landmark feature on the left hand side of the 'eye' crater appears to be similar...maybe? Thanks for your reply.
