These here cards are called sketchagraphs and are a subset to the Star Wars Galaxy 7 card set that will be released by Topps next month. Each card has an autograph by an actor or production person from any of the Star Wars movies and the animated Clone Wars series.
These autographs include Peter Mayhew (Chewbacca), Carrie Fisher (Princess Leia), Alan Flyng (an Executive Imperial Officer and wardrobe designer), Ashley Eckstein (Asohka Tano-Clone Wars), James Arnold Taylor (Obi-Wan Kenobi-Clone Wars), Timothy Zahn (author-Extended Universe), Ben Burtt (various small roles and sound engineer), Tom Kane (Yoda-Clone Wars), Matthew Wood (General Grievous), Mark Hamill (Luke Skywalker), Dickey Beers (various roles), and Catherine Tabor (Padme-Clone Wars).
Much thanks to my buds Jay Shimko and Scott Toth with help on deciphering some of these signatures!
