1. Gotham City Sirens #1 Cover by Guillem March
I don't know how many times I have to say it. I'm a sucker for cheesecake, and Guillem March delivers some of the best. Gotham City Sirens is essentially a nerd's wet dream. There's no point in denying it. Three of the sexiest ladies in the DC Universe team up and are drawn by Mr. March to great success. That being said, the cover is no different. While there was an excellent variant done by JG Jones that featured Catwoman front and center, March's depiction of the three buxom villanesses posing atop a Gotham searchlight is appropriately representative of the content you'll find within.
All three characters are given equal screen time, as well as equal importance. While the story (and covers) will certainly progress to have a rotating "leading" character, this cover work is prime for an introductory issue, as it features all three prodominately, leaving little confusion as to their roles in the title.
That, and March's work is just plain hot.
