See, now and then a comic might get published with a blank variant cover made from hard stock paper, the purpose being for commissions, presumably from a well-known comic artist visiting a convention (or your 2-year-old who likes Batman). I took a slightly less orthodox approach and handed my comic over to a friend.
Don't take this notion lightly. This was a paid commission (in various terms), but it was worth every penny. And, while everything comes with a price, I'm sure she'll be up for earning a bit of cash for commissions if you just drop her a PM.
Without further ado, this is the lovely Lady Kopaka's fantastic, wonderful, too-good-for-words-like-those-raptors drawing of Batman and Superman on Batman/Superman #1, N52, published in June.
I especially like how the capes flow with their length. And the backgrounds for each character. And the attention to detail, like Clark's t-shirt instead of his suit since that's what he has in this issue.
Now I just gotta figure out how to frame this!
(Seriously though, send her a PM and see if she has the time for commissions. She likes making money off of her talent.)
