Revelations of Mars had a wonderfully successful Kickstarter which reached Funded status very quickly.More artwork appeared through the Kickstarter page (which can be found here).
Some of the art is actually a bit racy (like this green woman). If there is an abundance of artwork like this, it might cause some problems with some of the more conservative customers.
