Here's the first pass at the backs of the Belle of the Ball cards. This branding is based on vintage labels, 19th century hand lettering, old Hollywood musicals, and a touch of wedding invitations.
I'm trying to create a general vibe that is inspired by Victoriana, but isn't tied down to one time period in particular. That gives artists license to mix anachronistic fashions and fits the inspiration for the game. (The "Shindig" episode of Firefly.)
I didn't record my process for this design, but you can see the elements I used here, here, here, and here. You can also see the black and white vector on the right.
