Lackadaisy

This is one of the most interesting online comics I've seen! Lackadaisy is a 1920s story about an "underground" bar during Prohibition. All of the characters are portrayed as anthropomorphic cats who not only dress accordingly for the time period, but also have the slang down perfectly. It's a wonderful treat that I strongly recommend. You can check out the comic HERE, or browse Tracy's Deviantart site HERE.
