BBV Productions have tweeted a pair of bookmarks, or I suppose if you put them back-to-back, a double-sided bookmark. Below is the one featuring what increasingly seems to be the cover for Auton, alongside those for Cyberhunt, Cybergeddon, Republica, The Rani Reaps The Whirlwind and The Airzone Solution.

Auton is available for pre-order with two other books here if you are in the UK and here if you are not.
