This was a lot of fun to do and I have to say Rob was a great guy to work with! We wound up going for a Punk-Rock Cowgirl for the poster, and I was influenced heavily by Western movie posters at first, which led me to a more rockabilly-meets-classic horror look to the poster in the end. For the girl we agreed it would be awesome if the end of the branding iron was the Liberty Bell to keep well of the fact that the band was from Philly.
Actually, in the background, you can see the original pencil art! I talked to a friend of mine who said the original pencils were awesome and I should use them somewhere in the piece, and I figured the background was a great place to put it since it helped tie everything together.
