2 of the Solos used on the Huddersfield Free Town Bus are named Pinky and Perky. I think this is a legacy from before K-Line was bought by what is now Yorkshire Tiger. Honley depot also personalised a few of their solos, with pictures of cartoon/comic characters by the doors. There was a Roadrunner, a Daffy Duck and a Batman. I have no idea if they had permission to use said characters!
