I've already mentioned this in the comments section of another post, but I wanted to say "up front" that we've uploaded a number of new cover illustrations to the Pyr blog. You can see the full cover spread for Alan Dean Foster's Sagramanda and Justina Robson's Mappa Mundi, as well as the front cover to Ian McDonald's Brasyl.
Artwork for Mappa Mundi and Brasyl is by Stephan Martiniere. Sagramanda is courtesy of John Picacio. Design on all three are by Jacqueline Cooke. Nice, no?
