With the release this week of DC Comics' Green Lantern Corps #40, artist Bernard Chang has announced he'll be giving away his original interior art from that final issue.

"Issues 21-40 have been some of the most challenging and yet rewarding work of my career," he wrote on Instagram. "As a show of my appreciation, I am going to give away ALL of my original interior art pages from the historic final issue 40 to you! I am cutting up all the pages into individual panels (except pgs 17, 19, 24-25, and 28, which will be raffled off)."

As he explains, all a fan has to do is buy two copies of Green Lantern Corps #40 -- one to keep, and one to give away. Take a photo of yourself holding the two copies, either inside or outside your comic store, and post it to Instagram with the appropriate tags (they're detailed in his post). You'll also have to direct-message Chang with a separate photo with the receipt to verify.

He'll accept entries through this weekend, or until he runs out of panels. On Monday, he'll raffle off the remaining whole pages to those who participated -- and he'll even pick up shipping costs.

a big thanks to all the #greenlanterncorps fans and my teammates over the last two years!!! issues 21-40 have been some of the most challenging and yet rewarding work of my career. as a show of my appreciation, I am going to give away ALL of my original interior art pages from the historic final issue 40 to you!!! I am cutting up all the pages into individual panels (except pgs 17, 19, 24-25, and 28, which will be raffled off). all you have to do is buy two copies of glc40, keep one and give one away to a friend (or stranger) in your store. Instagram a picture of you holding both copies either outside or inside your local comic book store. you must also include tags: @thebernardchang #greenlanterncorps40 and # (name of your comic book store or Instagram/Twitter handle, like #ultimatecomics or @ultimatecomics ). then, direct message me on Instagram w a separate picture of the receipt to verify your purchase (you will have to add me and turn your profile to public so I can verify). I will accept entries thru this weekend 3/16 or until panels run out (approx 65-70). on Monday 3/17, I will raffle off the remaining whole pages to all who participated in this contest. sorry, but this is limited to hard copy sales (no digital) and only in the US. I will cover all shipping costs.
