Brand Identity Concepts For A Burger Restaurant

Initial brand identity concepts for a burger restaurant we are currently working on. We start every branding project with 3 concepts, and then refine the chosen concept over 3 rounds of revisions. Our client wanted to personify their burger brand with a mascot, so we created 3 different hand drawn options to choose from. The overall creative direction for the project is mid century, nostalgic, Americiana fast food.

Which concept would you choose?
