Randy Martinez has a few of his original line art drawings for the 2013 Illustrated Topps trading cards for sale on his Storenvy shop. There are several available, but only three that feature the Millennium Falcon. This one is called “The Rebellion’s Imminent Victory” and is of Luke’s X-Wing as he fires the torpedo that scuttles the battle station.
This one is 11″ by 17″ and is available to buy for $600.
Here’s the full colour trading card that was released by Topps.
