With today's release of The Flash #5, I received the final (12 of 12) White Lantern variant cover. Thanks to Borderlands Comics & Games, I have all twelve! Here is a (poorly made) video I put together showing them off. Below the video, you will find a link to see a nice version of the big picture on the DC Universe blog.
