Here is my proposed logo for the new look of the Tour de Brews! --> #9
I wanted it to be both fun and professional, while feeling retro/vintage like you requested. I also included a grunge version, which really pushes the vintage feel to the next level: #10. And then for good measure, I mocked it up on blue as well: #11.
Let me know what you think, and we can go from there. Thanks!
