I don't watch much Scooby-Doo these days, the new animated series doesn't really look very good, but my kids seem to love it. I always thought it would be fun to see someone take these character and give them a different feel, tone and setting. Artist Alexander Kuhn has done just that, he created this cool series of retro 1950's character designs. I could see this being a fun series. I especially like the old Woody Mystery Machine.
