First, Mass Effect action figures gave you DLC. Now buying an art book will grant you the same thing.
If you pre-order the new art book for Mass Effect, titled "Art of the Mass Effect Universe", you will receive a code that allows you downloadable content for Mass Effect 3 on either the PC or Xbox 360. What the content is is unknown at the moment, but we know that one is a collector's rifle.
You can pre-order your copy now at Barnes & Noble.
