Attack of the Killer "B's": Artgerm to Cover Supergirl #12 and #13

DC’s cover priced variants featuring some of the hottest artist has been a pretty big success. Many of the covers have become scarce right off the bat. Looks like a fan favorite artist returns in August and September for Supergirl #12 and #13. 
According to DC’s sale sheet through Diamond, Stanley “Artgerm” Lau will do the B cover for Supergirl #13. One to watch for sure. Supergirl #12 is available for pre-order, but no image has been uploaded yet. Will update when #13 is available for pre-order.
Artgerm’s previous B cover, Wonder Woman #1, sells for $10-$14.
